Megabit Modem 310F and 320F User Manual Chapter 4: Configuring the Modems Configuring the Interleave Options It is important to note that an increase in impulse noise immunity causes an increase in delay. Use the interleave option to increase impulse noise immunity. The delay is in milliseconds for both the Up and Down Interleave Options (upstream and downstream traffic). 1 From the ADSL Configuration Menu (page 20), typeA to select Up Interleave Option. 2 Press the SPACEBAR to toggle to the interleave value you want, then press ENTER . The available options are 0, 2, 4, 8 and 16 msec. The recommended interleave delay is 4 msec, to achieve maximum transmission rates with adequate noise immunity. The default is 4. 3 Type B to select Down Interleave Option. 4 Press the SPACEBAR to toggle to the interleave value you want, then press ENTER . The available options are 0, 2, 4, 8 and 16 msec. The recommended interleave delay is 4 msec, to achieve minimum latency with adequate noise immunity. The default is 4. Saving ADSL Configuration Changes After you make changes to ADSL configuration from the ADSL Configuration Menu (page 20), you must either accept or not accept these changes before you can return to ADSL Menu (page 20). 1 When you finish making changes to ADSL configuration, typeM or R to exit the ADSL Menu. The following prompt displays: Save current settings (Y/N)? 2 Type Y to save the changes you made or type N to not save the changes you made. You return to the ADSL Menu. Megabit Modem 310F and 320F User Manual Configuring ADSL Service Resetting the ADSL Link After you make any ADSL configuration changes, you must reset the ADSL link to activate the new configuration and reestablish the ADSL link. 1 From the ADSL Menu (page 20), type6 to reset the ADSL link. The following prompt displays: This will bring down the ADSL link. Are you sure (Y/N)? When you select yes, the modem automatically resets the ADSL link between the Megabit Modem 310F and 320F. You are automatically logged off the modem(s) and must log on again. Do one of the following: • Type Y to reset the ADSL link. The following message displays: ADSL link reset • Type N if you do not want to reset the modem. (If you do not reset the modem, ADSL configuration changes you made are not activated.) Megabit Modem 310F and 320F User Manual Chapter 4: Configuring the Modems CONFIGURING BRIDGE PARAMETERS Configure the Ethernet bridging parameters. The LAN mode for the Megabit Modem 310F and 320F is half duplex. On the Main Menu (page 11), type 3 to display the Bridge Menu. 09/09/99 PAIRGAIN TECHNOLOGIES 03:36:55 ATU-C ADSL MEGABIT MODEM TERMINAL v 1.0 BRIDGE MENU LAN LINK STATUS UP 1.

SOURCE ADDRESS DATABASE MENU (M)ain ENTER CHOICE--> Configuring Bridge Aging Time The Bridge Aging Time determines the interval at which the modem checks the bridging table for unused addresses and marks those addresses as invalid. The default is 300 seconds. 1 Type 2 to select Bridge Aging Time. 2 Type the value in seconds (valid range is from 1 to 511) that you want, then press .ENTER Megabit Modem 310F and 320F User Manual Configuring Bridge Parameters Configuring the Source Address Database The source address database can contain up to 8,192 entries. Addresses can be entered either automatically through address learning on the LAN port, or manually. Each address is mapped to a 10-bit key, which is used to group the addresses into 1,024 separate buckets containing up to eight addresses in each bucket. This reduces the search time required to locate an address in the address table by requiring the processor to search only one bucket, or a maximum of eight addresses. 1 From the Bridge Menu, type 4 to display the Source Address Database Menu. 08/12/99 PAIRGAIN TECHNOLOGIES 03:45:44 ATU-C ADSL MEGABIT MODEM TERMINAL v 1.0 SOURCE ADDRESS DATABASE MENU 1.
