hRemote In-band Loops: Enabled (default)

Options: Enabled, Disabled

In ESF, D4 and Unframed formats, the unit can respond to special repeating codes in the data stream that represent loopback com- mands. The command to loop up (go into loopback) is a repeating pat- tern of 00001s. This pattern overwrites the normal data. When this code is detected for 5 seconds, the unit will go into loopback if the Remote In-band Loopback is Enabled. When a repeating code of 001s is received for 5 seconds, the unit loops down (goes out of loopback). The delayed recognition guards against false starts, since the code must be present for a long time continuously. When Disabled, the unit will recognize the codes but will not respond to them. The loopback timeout also applies to this feature.

iV.54 Loops (RDL Only): Enabled (default)

Options: Enabled, Disabled

This is a special in-band loopback facility that sends a special pseudo-random pattern over the data stream. This is the only remote loopback that the unit can initiate. This is useful for campus applica- tions when you need to put a remote unit in loopback. The remote unit responds to the V.54 loopback command, and the whole process takes only a few seconds to complete. This setting will enable/disable RDL from being initiated from either the control port or the DTE interface. It will also enable/disable the unit to respond to the V.54 command if received over the line. The duration of the loopback is limited by the loopback timeout setting. (See Unit Operations, paragraph 3.2.4, on pages 32 and 33.)

jDefault Config Source: Switch (default)

Option: EEPROM, Switch

The Model 2720 can be initialized via the configuration in the on- board permanent memory (EEPROM) or via the internal DIP switches (Switch). Once the unit is powered up, you may change the settings through the control port or the DIP switches.

If you do not have a terminal, you may force the unit to use the DIP switches as the default configuration source by turning off the unit, setting all the DIP switches to the ON position, then powering on the

unit. This will cause the unit to enter a special mode. Then turn off the unit and change the switch settings to the desired settings. When you turn the unit on again, the unit will be set up with the selected switch settings.

nDS0 Channel Configuration Menu: [ Bandwidth/# Channels = 1,536/24 ] (default)

The DS0 Channel Configuration Menu has a sub-menu that looks like this:

You may configure the Model 2720 to operate with any combina- tion of active and inactive DS0 channels in this screen. When you exe- cute the Save Changes command, the selected settings will be saved to permanent memory, and the system will be updated to operate with the new channel settings.

NOTE: In Unframed format, the Bandwidth Selected will display “1,544k,” and the Total Channels will display “n/a.” When the DS0 Channel Rate is 56kbps, the Bandwidth Selected will be a multiple of 56k, not of 64k. When using the DIP switches to set the band- width, the starting channel is always channel 1.
