Annex L Annex M Annex I

Note: The subscriber cannot use POTS or ISDN services when you enable Annex I.
PMM Enable the Power ManageMent (PMM) feature to reduce the amount of power used overall and reduce the instances of the connection going down. PMM increases or decreases the transmission power based on line conditions. PMM also decreases the number of service interruptions. Select L2 to have the ADSL connection use power saving mode and reduce the rate when there is no traffic. The rate comes back up when there is traffic. Select L3 to use both power management modes L2 and L3. L3 puts the ADSL connection to sleep mode. L0 power mode uses no power reduction. See the ITU-T G.992.3 standard for more on PMM and the power modes (states). SRA Enable Seamless Rate Adaptation (SRA) to have the IES-1248-51V automatically adjust the connections data rate according to line conditions without interrupting service.

LABEL DESCRIPTION

Sudden spikes in the lines noise level (impulse noise) can cause errors and result in lost packets. Set the impulse noise protection minimum to have a buffer to protect the ADSL physical layer connection against impulse noise. This buffering causes a delay that reduces transfer speeds. It is recommended that you use a non-zero setting for real time traffic that has no error correction (like videoconferencing). US INP DS INP Max US TX PSD Max DS TX PSD L0 Time L2 Time L2 ATPR Set the minimum upstream (US) impulse noise protection setting. Set the minimum downstream (DS) impulse noise protection setting. Specify the maximum upstream transmit power (-256 ~ 255 in 0.1dBs). Specify the maximum downstream transmit power (-256 ~ 255 in 0.1dBs). Set the minimum time (in seconds) that the ADSL line must stay in L0 power mode before changing to the L2 power mode. Set minimum time (in seconds) that the ADSL line must stay in the L2 power mode before reducing the power again in the L2 power mode. Set the maximum Aggregate Transmit Power Reduction (ATPR) in decibels (dB) that is permitted in a L2 power reduction. The system can gradually decrease the ADSL line transmission power while it is in the L2 power mode. This is the largest individual power reduction allowed in the L2 power mode. Set the maximum Aggregate Transmit Power Reduction Total (ATPRT) in decibels (dB) that is permitted in the L2 power mode. This is the total transmit power decrease that is allowed to occur in the L2 power mode. Set the maximum transfer rate (in Kilobits per second) that is permitted while the port is in the L2 power mode. The supported range is 32~4096 Kbps in 4 Kbps increments. If you enter a number that is not a multiple of 4, the system uses the next lower multiple of 4. If you enter 39 for example, the system will use 36. Set this to 0 to have the system automatically assign a value. Set the minimum transfer rate (in Kilobits per second) that is permitted while the port is in the L2 power mode. The supported range is 32~4096 Kbps in 4 Kbps increments. If you enter a number that is not a multiple of 4, the system uses the next lower multiple of 4. If you enter 39 for example, the system will use 36. Set this to 0 to have the system automatically assign a value. Set the down stream transfer rate (in Kilobits per second) that serves as the threshold for whether the port is to use the L0 or the L2 power mode. The system changes from L0 mode to L2 mode when the downstream transfer rate stays below this threshold for L0 Time. The system changes back from L2 mode to L0 mode when the downstream transfer rate goes above this threshold. This rate must be less than or equal to one half of the Min L2 Rate and at least 16 Kbps. Set this to 0 to have the system automatically assign a value.

IGMP Filter Profile Click IGMP Filter Profile to open the IGMP Filter Profile screen where you can configure IGMP multicast filter profiles (see Section 20.7 on page 180). Index Name Encap AAL This is the number of the VC profile. This name identifies the VC profile. This field displays the profiles type of encapsulation (LLC or VC). This field displays the ATM adaptation layer used by the VC profile. aal5 - The VC profile uses ATM adaptation layer 5. Class This field displays the type of ATM traffic class: cbr (constant bit rate), vbr (real-time variable bit rate), nrt-vbr (non-real time variable bit rate) or ubr (unspecified bit rate). This is the Peak Cell Rate (PCR), the maximum number of cells that the sender can send per second. This field displays the accepted tolerance of the difference between a cells transfer delay and the expected transfer delay.

This chapter shows you how to configure the Voice over Internet Protocol (VoIP) features on your IES-1248-51V.

45.1 VoIP Overview

VoIP (Voice over IP) is the sending of voice signals over the Internet Protocol. This allows you to make phone calls and send faxes over the Internet at a fraction of the cost of using the traditional circuit-switched telephone network. You can also use servers to run telephone service applications like PBX services and voice mail. Internet Telephony Service Provider (ITSP) companies provide VoIP service. Circuit-switched telephone networks require 64 kilobits per second (kbps) in each direction to handle a telephone call. VoIP can use advanced voice coding techniques with compression to reduce the required bandwidth. The IES-1248-51V connects POTS (Plain Old Telephone System) end-user telephone subscribers to the IP network by converting the analog voice signal into data packets and transmitting them over the network.
45.1.1 Introduction to H.248
The H.248 protocol, also known as MEGACO (MEdia GAteway COntrol) or the Gateway Control Protocol, defines a VoIP network in which basic functions (such as voice coding and decoding) are performed by one device, and higher functions (such as setting up and managing calls) are performed by another. The H.248 protocol was developed jointly by the IETF (Internet Engineering Task Force) and the ITU (International Telecommunication Union). It is defined by the IETF in RFC 3525, and by the ITU in ITU-T H.248-1. An H.248 VoIP network has a single intelligent control unit, which manages a network of dumb endpoint devices. An H.248 VoIP network consists of one or more media gateways and a media gateway controller.
Chapter 45 VoIP Media gateways (MGs) encode and decode voice data, transmitting it from one network to another (for example, from the PSTN to an IP network, and vice versa). The H.248-enabled VoIP line cards are MGs. Media gateway controllers (MGCs) are intelligent devices that manage the media gateways. They set up, manage and tear down calls by providing instructions to the MGs. In the following example, the MG allows the users of analog telephone C and IP telephone D to communicate by reporting events to the MGC 1 (for example, if the user of phone C dials a sequence of numbers). The MGC 1 interprets the information according to its programming and issues the relevant commands to the MG (for example, telling the MG how to connect phones C and D in a call, or telling the MG to play a busy tone to phone C). See Section 45.1.4 on page 319 for a detailed example of H.248 call progression. For increased reliability, the MG can use a second MGC 2 if it cannot reach the MGC 1.

Chapter 61 IP Commands The following is a list of general IP commands that help with the management of the IP parameters.
Table 172 General IP Commands
ip set <ip-address> [/maskbits]
Configures a static IP address for the IES-1248-51V management through Ethernet and SFP ports. If you dont enter the subnet mask, the system automatically computes one. Enables DHCP client, has the DHCP server reassign a new IP address or removes the current dynamic IP address on the IES-1248-51Vs Ethernet and SFP ports for management. Changes the default gateway (next hop). This tells the IES-1248-51V where to send packets that have a destination IP address that is not on the same subnet as the IES-1248-51Vs IP address. Displays the current management IP settings. Displays the current management IP settings, the IES1248-51Vs routing table, and the IP Address Resolution Protocol (ARP) table. Checks for network functionality by sending an echo request to another IP host and waiting for the reply. voip: use the VoIP interface.

Defines a new, static IP forwarding route or edits an existing one. Configures the default static IP forwarding route. Removes a static IP forwarding route. Displays the IES-1248-51Vs routing table. Clears the routing table. Displays the IES-1248-51Vs IP Address Resolution Protocol (ARP) table. This is the list of IP addresses and matching MAC addresses that the IES-1248-51V has resolved. Clears the IES-1248-51Vs IP Address Resolution Protocol table. Shows the statistics for the CPU IP traffic.

H/H H/H M/L H/~ M/L

This command displays routing table entries created manually for the specified domain and/or range of IP addresses. It does not show entries added automatically by the IES-1248-51V. This command displays the (run-time) routing table(s) for the selected domain or range of IP addresses. This table includes all the entries, whether added automatically by the IES-1248-51V or provided manually. This command deletes the specified entry from the routing table of the specified domain. You can only remove entries that were added manually.
62.4.1 IP Bridge Route Set Command Example
The following example creates an entry in the routing table for domain example3. This entry forwards traffic for IP addresses 192.168.4.0~192.168.4.255 to edge router 192.168.1.244.

Chapter 63 SNMP Commands

sys snmp trapdst set <index> <ip-address> [<port>]
Specifies the IP address (and port number) of a trap server to which the IES-1248-51V sends SNMP traps. If you leave the trap destination set to 0.0.0.0 (default), the IES-1248-51V will not send any SNMP traps. index: The number of the trap server (1~4). port: The port number upon which the trap server listens for SNMP traps. The IES-1248-51V uses the default of 162 if you do not specify a trap port.
sys snmp trapdst del <index> sys snmp show
Removes the specified SNMP trap server setting. Displays the current SNMP get community, set community, trap community, trusted hosts and trap destination settings.

ADSL Commands

This chapter describes some of the ADSL commands that allow you to configure and monitor the ADSL ports.
64.1 ADSL Command Input Values
The following table describes the values required in ADSL commands. Other values are discussed with the corresponding commands.
Table 183 ADSL Command Input Values
downdownshiftmargin down-maxmargin down-max-rate down-minmargin down-min-rate down-targetmargin fast|interlea ve[=<updelay>,<downdelay>] max-nominalpsd mx
The downstream down shift noise margin (0~31 dB).
The maximum acceptable ADSL downstream signal/noise margin (0~31db). The maximum ADSL downstream transmission rate (32~25000 Kbps). The minimum acceptable ADSL downstream signal/noise margin (0~31db). The minimum ADSL downstream transmission rate (32~25000 Kbps). The target ADSL downstream signal/noise margin (0~31db). The latency mode. With interleave, you must also define the upstream and downstream delay (1~255 ms). It is recommended that you configure the same delay for both upstream and downstream. Maximum nominal transmit PSD (Power Spectral Density) measured in 0.1dBm/Hz. The downstream carrier tones to be masked (disabled). Each <mx> can use up to 8 hexadecimal digits (00000000~ffffffff). Each <mx> represents 32 carrier tones (each hexadecimal digit represents 4 tones). The hexadecimal digit is converted to binary and a '1' disables the corresponding tone. Disabling a carrier tone turns it off so the system does not send data on it.
