Test Configuration Options

V54 Address: Disable

Nxt Disable (Address Values)

V.54 Address. Determines which remote 3800 Series modem is placed into a remote loopback test. This can be either a remote digital loopback or local analog loopback. This type of addressing can be used for extended data circuits (tail circuits).

Disable – This is used for normal point-to-point dial and leased-line networks.

Address Values – 01, 03, 05, 07, 09, 0B, 0D, 0F, 11, 13, 15, 17, 19, 1B, 1D, 1F, 25, 27, 2B, 2D, 2F, 33, 35, 37, 3B, 3D, 3F, 55, 57, 5B, 5F, 6F, 77, or 7F. This configuration option selects the address of a modem that is to be placed into a loopback test. This configuration option is used for more complex networks where multiple modems, used in extended data circuits (tail circuits), can be commanded to loopback.

CAUTION: Selecting an address will disable any remote loopback that can be commanded from a remote modem. The DTE must now control loopback via CT140 and supply the address.

The factory default is Disable.

AT command for Disable is S-register S53 = 0.

AT command for V.54 Address is S-register S53 = n, where n is a value from 1 to 34.

V54 Device Type: Peripheral

End Peripheral Intermediate

V.54 Device Type. Identifies where the modem is physically located in the network.

Peripheral – The modem is located at the endpoint of the network and is not connected back-to-back with another modem.

Intermediate – The modem is either of the two modems connected back-to-back.

NOTE: This configuration option is only available if V54 Address is enabled.

The factory default is Peripheral.

AT command is S-register S54 = n, where n is 0 for Peripheral and 1 for Intermediate.
