Introduction

This bulletin provides notification of the pending Retirement (or Manufacture Discontinuance) the *Meridian Digital (Modular) telephone series. These sets have also been known as the Aries line and, more recently, as the M2000 series (not to be confused with the previous M2000 line of M2009, M2112, M2018 sets that have already reached End-of-Life). The Meridian Digital (Modular) series of phones were originally launched in 1989 and have enjoyed a 15 year lifespan. These sets have proven to be a popular and reliable series in the field. As part of the commitment to its Evergreen investment protection philosophy, Nortel Networks has provided full support on these sets on every software release since introduction Due to their long lifespan, some hardware components are now reaching obsolescence and Nortel Networks may not be able to guarantee availability of these sets, or the quality of sourced components, into the future. Nortel Networks is therefore providing notice that the Meridian Digital (Modular) series of digital sets will be retired from their respective price catalogs in October 2004 and will not be available for purchase from Nortel Networks after that time. Repair and Replacement service (chargeable) will remain in effect during the retirement period. The normal retirement period for telephone hardware is three (3) years from the date of retirement to end-of-life. The Meridian Digital (Modular) telephone series is targeted to move Page 1 of 4
into End Of Life status no later than Q4 2007. Upon End of Life, repair and replacement service will no longer be available. NOTE Specific models of Meridian Digital (Modular) sets have already been retired in certain market Regions, notably EMEA. This Bulletin announces the minimum global life cycle rating for this product and does not supercede any previous Regional actions. Please check with your local Nortel Networks representative if you require further clarification. NOTE the M2016S Secure set is currently excluded from this Notice of Manufacture Discontinue. The M2250 Console is also not included in this retirement action. Definitions Manufacture Discontinue Definition This notice serves as formal communication of Nortel Networks intent to manufacture discontinue (MD) the product(s) noted. No further orders will be accepted as of the date shown above. The MD of these products should not be interpreted as the discontinuance of any Nortel Networks agreements to support the existing field population. Services to the existing product base will continue to be provided until the End of Life (EOL) date shown above. End-Of-Life Definition This notice serves as formal communication of Nortel Networks intent to end the life of the product(s) noted. No further support will be provided. Emergency recovery and/or upgrades may be performed in accordance with customer specific service plans or upgrade agreements as negotiated prior to EOL.

Customers also have the option of adopting IP Telephone solutions with Nortel Networks i2000 series portfolio. The i200x series of IP Telephones delivers the rich feature set of the M3900 series in tandem with benefits in administration (simpler adds, moves and changes with IP Phones) for reduced costs. The i200x series of IP Telephones also offer customers the ability to deliver new and valued services to users.

Software Dependencies

During the period of Retirement (MD), telephone sets are fully supported on all applicable software releases (Current, Active and Sustained releases) until the telephone sets are deemed End-Of-Life. Customer Support is available for these sets. Repair and replacement service (chargeable) is also available. All feature functionality is expected to be retained at the same level as was valid at the time the sets were Manufacture Discontinued. Any new feature functionality introduced by system software after the time of set Retirement will not be designed to function on the MDd sets. Technical support for any such new functionality will not be provided on MDd sets. NOTE the recommended Digital set replacement is the M3900 series. The M3900 sets were first introduced and supported on X11 Release 24.24 / 24.25, however Release 25 software is recommended. While the minimum recommended release is 25.10 or, in Regions where it was Page 3 of 4
introduced, Release 24C (25.08) - to obtain full M3900 feature functionality, Release 25.40B, or later, is recommended. In addition to delivering M3900 Phase 3 feature developments and fixes, this level of software provides the ability to download new versions of M3900 firmware to the switch/server when such firmware is made available. Prior to MD of the Meridian Digital (Modular) telephone series, Release 24 will have also moved into Retirement (October 2004). All previous X11 software releases will be in End-Of-Life status. Therefore, customers requiring support must reside on X11 Release 25 (Release 25.40B recommended) or Succession 3.0 Software. At this level, they will be able to deploy the latest versions of M3900 sets and firmware. Customers seeking to deploy i200x series of IP Telephones must reside on X11 25.30 or later software.

Connections

The line cord connects to the rear of the M2250 attendant console through a 25-pin subminiature D-type connector. The jack connector is attached to the line cord for user safety and equipment protection (pins are not exposed). Having the plug connector mounted in the console also prevents interchanges between the line cord and the serial data port connectors (the serial data port in the console has a jack connector). Identical two-prong G3 type connectors are provided on each side of the console body to permit handset or headset connection at either side of the console. The M2250 attendant console is compatible with both carbon and electret handsets or headsets. The electret handset plug is orientation-dependent and is labeled accordingly. The attendant console is connected to the system through two digital ports one port for Call Service processing and one for Call Destination processing with three additional ports for powering, for a total of five ports. The PCCIU interface used for the PC-based Console software application requires only three ports in total. The attendant console requires a Digital Line Card (DLC) or an Integrated Services Digital Line Card (ISDLC) NT8D02 or later.

Local console controls

Visual contrast on the display panel can be adjusted using the Contrast option on the Options menu. From the Options menu, four-line mode can be changed to two-line mode for easier viewing and to use larger fonts. The pitch and volume of the buzz tone on the console can be adjusted by the user. Any one of 15 languages can be chosen for the console screen displays: English, French, Spanish, German, Italian, Norwegian, Irish (Gaeilge),

Page 57 of 504

Turkish, Katakana, P.R.C. (Peoples Republic of China), Taiwan, Korean, Polish, Czech/Slovak, or Hungarian. When the languages P.R.C., Taiwanese, and Korean are chosen, the attendant console uses two-line display. The attendant console is equipped with a real-time clock/calendar. The time of day (hours, minutes, and seconds) and the date (day, month, and year) are displayed on line 1 of the display screen. The sound of key clicks can be turned on or off. The pitch and volume of key clicks can be adjusted.

Wiring

The M2250 attendant console requires a 16-pair cable terminated on an Amphenol connector. When zone cabling and conduit are used, assign a block of numbers or letters to each zone. Allow for growth when assigning blocks of numbers. Cable markers are normally an adhesive-backed cloth tape 1/2 inches wide by 3-1/2 inches long (15 mm by 65 mm) with preprinted numbers. For limits and cabling for analog (500/2500-type) telephones, refer to Figure 12 on page 58. For a list of terminal connections, see Table 5 on page 59.

Upon receiving the first flash data packet, a page status bar is displayed (see Figure 46). Depending on the language files being downloaded, there are three or four memory pages that are downloaded (three for North American, four for Global, Eastern/Western European versions). As additional flash data packets are received, the status bar advances to the right until the current page is completely programmed. Once the next page starts to download, a new page block is displayed and the status bar starts from the left again. This process is repeated for the remaining pages. If the download was unsuccessful, the telephone displays a telephone icon with an X through it. This indicates that the flash memory is not programmed (or is corrupt) and a new download must be initiated.

Configuration parameters in LD 32
To use the Flash Download capability, load LD 32 and issue the following commands.
Single-Set Flash Download
Flash DownLoad Unit (FDLU) - Initiate flash download for this unit. For this command to work, the telephone must be in an idle state. That is, there

Page 275 of 504

can be no active call, no active application, and the telephone must be configured and in working condition (responding to a query command). Also, the firmware version on the telephone must not be current. That is, it must be different from the one on the system disk. FDLU l s c u l = loop address s = shelf address c = card address u = unit address Flash DownLoad Idle (FDLI) - Initiate flash download as soon as the telephone is idle. For this command to work, the telephone must be in working condition. If the telephone is idle, the downloading occurs immediately. If the telephone is on an active call, downloading occurs immediately after the call is terminated. However, if after the active call is terminated, there is an active application on the telephone, downloading is aborted. Again, the downloading operation occurs only if the version on the telephone is not current. FDLI l s c u Flash DownLoad Forced (FDLF) - Initiate flash download immediately. For this command to work, the telephone must be in working condition. If the telephone is idle, the downloading occurs immediately. If the telephone is on an active call, the call is force disconnected and then downloading occurs immediately after the disconnect. It also force downloads the system disk version even if the telephone firmware version is more current. However, if there is an application active on the telephone, the downloading operation is aborted. FDLF l s c u
System-wide Flash Download
To prepare and trigger the flash download for the whole system manually, access LD 32 and issue the following commands.

Page 276 of 504

Flash Download System (FDLS) - Initiate system-wide flash download based on the parameters specified in LD 97. This initiates the system-wide flash download to all, or the specified type of M3900 telephones, from the system disk if the flash firmware version on the telephone is different from the version found on the disk. During system-wide flash download, when flash download detects that an M3900 telephone is in an active call connection, the telephone is skipped. Download logic keeps track of skipped telephones, and comes back to attempt the download later. M3900 flash download attempts download to each telephone up to three times. If download does not succeed by the third attempt (whether due to an active call connection or some problem such as a transmission error), flash download to the telephone is considered to have failed. An appropriate message is displayed for each telephone that fails the firmware upgrade process. Upon completion of system-wide flash download, a completion message is displayed on the maintenance telephone. This operation can take up to several days to complete depending on the traffic load, the total number and distribution of the equipped M3900 telephones, and the scheduling of the download. See Table 39 on page 277 for estimations on download times. When M3900 telephones fail system-wide flash download, you can then determine the cause of the failure, perform corrective action, and repeat the flash download command system-wide or for a specific telephone.FDLS Flash Download Cancel (FDLC) - Cancel the system-wide flash download. From LD 32 or outside of the overlays, you can cancel or stop the system-wide flash download operation gracefully by issuing the FDLC command. A download in progress to the current telephone(s) completes before the download process terminates.FDLC

Measuring Impulse Noise
Use Procedure 51 on page 302 to measure impulse noise.
Procedure 51 Measuring impulse noise 1 Measure impulse noise on selected lines during busy hours. Use an NE 58B noise measurement set or the equivalent. Note: The termination and weighting filter required are 135 ohm and 100 kHz, respectively, and the blanking interval is 25 s. 2 Using Figure 48, determine that for a given loop loss and noise threshold the impulse noise counts for each 15-minute interval are below the corresponding curve. Note 1: The values in Figure 48 were derived by assuming that the counter has a count rate or 512 pulses per second. Note 2: Because of the inaccuracy of the noise-measuring set, additional errors can occur during the blanking interval, and the reading consequently is lower than the actual measurement.
Measuring Background Noise
Use Procedure 52 on page 302 to measure background noise.
Procedure 52 Measuring background noise 1 Measure background noise on the loop by using an NE-58B noise-measuring set. Note: The weighting and termination to be used are 100 kHz flat and 135 ohm, respectively. 2 Reject the loop being tested if the measured background noise is not less than 51 dBrn.
Calculating Expected Pulse Loss
Use Procedure 53 on page 304 to calculate expected pulse loss.

Digital telephones line engineering Procedure 53 Calculating expected pulse loss 1 Collect loop makeup data between the line card and the terminal. For each cable section, the data required is: 2 cable type (PIC or pulp) gauge length type of plant construction (underground, aerial, or in-building)
Calculate individual cable section losses by using the figures in Table 42 on page 305 through Table 44 on page 306, and the following equation: CSLi = SLi x Li CSLi = cable section loss for section i SLi = section length of section i Li = loss per unit length for section i
Correct individual cable section losses for maximum cable temperature by using the following equation: TCLi = CSLi x TCFi TCLi = temperature corrected loss for section i TCFi = temperature correction factor for section i Correction factors: aerial cable TCF = 1.1 underground cable TCF = 1.04 in-building cable TCF = 1

All of the Meridian Modular Telephones are equipped with: Hold key Release key Volume control Message Waiting lamp Speaker
Each modular telephone also has a number of programmable keys with LCD indicators that can be assigned to any combination of directory numbers and features (only one DN for the M2006). The lower right-hand key (key 0) is reserved for the Primary DN. When equipped with a Display module or MCA, key 07 is automatically assigned as the Program key and cannot be changed. Key 05 becomes the Program key on the M2006, if equipped with MCA. The M2006 is a single line telephone and accepts only one DN. The remaining five key/lamp pairs can be assigned any feature that is not considered a DN, such as Transfer, Call Forward, or Conference. Features that cannot be assigned are those that are considered DNs: Voice Call and 2-way Hotline, for example. Attempting to assign more than one DN to the M2006 causes the telephone to disables itself and all LCDs light steadily. It will return to its normal operating state when service change removes all secondary DNs. LCD indicators support 4 key/LCD states: Function LCD state idle off active on (steady) ringing flash (60 Hz) hold fast flash (120 Hz) * An indicator fast flashes when a feature key is pressed but the procedure necessary to activate the feature has not been completed.

Handsfree operates as if an off-hook operation had been performed. For example, when the telephone is idle, pressing the Handsfree/Mute key turns on the Handsfree and selects a DN (depending on line selection as assigned through COS), enabling the user to make a call. When a call comes in to an M2008HF/M2616 and the set is ringing, pressing the Handsfree/Mute key turns on the Handsfree and enables the user to answer the incoming call (depending on COS-assigned line selection) without picking up the handset.

A 2-line by 24-character Display Module provides system prompts, feedback on active features and valuable calling party information. In addition, you can modify various set features such as volume and screen contrast using the Program key (top right function key). You can enable a Call Timer which times calls made or received on the prime DN. Note: The Display Module is not supported on M2006. Note: The Display Module requires a Power Supply Board on M2008. Two types of Display Module are available: North American Display Supports normal business features in two languages, English and Quebec French. Special Applications Display Supports the following features: Automatic Call Distribution (ACD) Hospitality 6 languages (English, Quebec French, Parisian French, German, Spanish, Dutch) A Special Applications Display Module comes as standard equipment on the M2216ACD telephones. M2008 or M2616 telephones used as ACD telephones require the Special Applications Display. Note: It is possible to adjust the Display screen contrast so that it is too light or too dark to read. If you cannot read the Display, disconnect and then reconnect the line cord to return to the default settings.

Note: This section is for reference only. The telephone and options described in this chapter are manufacture discontinued and no longer available.
Use proper care when unpacking any add-on module. Check for damaged containers so that appropriate claims can be made to the transport company for items damaged in transit. If a module must be returned to the factory, pack it in the appropriate container to avoid damage during transit. Remember to include all loose parts in the shipment. There are three distinct versions of Meridian Modular Telephones all three are supported. The versions can be clearly distinguished by the first four letters in the upper left-hand corner of the model identification label on the bottom of the telephone. The three versions are as follows: the NTZK models the NT2K models with date code prior to April 24, 1998 the third version includes both the NT9K models and the NT2K models with date code of April 24, 1998 and later In addition, the two jacks face in the same direction on NT2K and NT9K telephones, and in opposite directions on NTZK telephones. When appropriate, differences between the models are noted in this document.
