Appendix I
128K Clear Channel Leased-Line Service
This appendix provides a description of commands used for
configuring the UTA220k for 128K Clear Channel Leased
Line (2B1Q) service.
Configuring D- and B-Channels
There are no D-channel activities in leased-line service;
therefore the TEI’s are disabled and DPIDs and DNs are
cleared for all ports.
The AT commands in this section let you:
•Disable TEIs and clear SPIDs and DNs
•Configure B-channels
Use the AT>Cn command, where n is a port number, for each
port in turn, to specify which port to configure. (The AT>C
command, without a number, ends control of any specified port
and specifies control of the physically-connected port.)
This Command... Does This:
AT!D3=127 Disables the TEI
AT!C2=”” Sets the SPID to an empty string
AT!N1=”” Sets the DN to an empty string
AT!C4=9 Sets the B1 channel for leased-line operation
AT!C5=9 Sets the B2 channel for leased-line operation
Example:
This command string disables the D-channel and sets the B-channels for
leased-line operation from Port 1.
AT>C2!D3=127!C2=””!N1=””>C!D3=127!C2=””!N1=””!C4=9!C5=9
