Calling Line Identification (CLID)
Sending a Calling Line Identification (callers extension number) to the dialed party over the ISDN D-channel is optional, and can be allowed (or not) per DN. DN's are associated with a CLID entry, which defines the CLID data. To create CLID entries, edit NET_DATA in LD 15:
LD 15 REG: chg TYPE: net_data CLID yes - SIZE - ENTRY # -- DIDN (yes or no)
ENTRY # is the CLID entry to be configured. CLID entries must be between 0 and and the value entered at the SIZE prompt - 1 (default 255). Precede entry or entries with X to delete. ENTRY is repeated until <cr> is entered.
ENTRY 0 is the default assignment to a DN in LD 10 or 11, edit this as required:
- KEY # SCR XXXX 0 <- last number is the entry number
Use LD 21 to print the CLID entries - REQ: PRT, TYPE: CLID.
In the entry examples below, ENTRY 0 will not pass the extension number in CLID and ENTRY 1 will pass the extension in CLID.
LD 21 REQ: prt TYPE: clid CUST 0 SIZE 256 RNGE ENTRY 0 HNTN <- Area Code HLCL <- Local prefix, or listed directory number DIDN NO <- NO, don't append the DN to the HNTN/HLCL HLOC LSC CLASS_FMT DN ENTRY 1 HNTN HLCL DIDN YES <- YES, append the DN to the HNTN/HLCL HLOC LSC CLASS_FMT DN
|HLCL||- local prefix (Home LoCaL), or listed directory number (1-12 digits) - precede with X to remove|
|DIDN YES||- precede the DN of the active DN key with the digits in HLCL|
|DIDN NO||- do not append the DN of the active DN key, HLCL only.|
The carrier company may send thier HLCL, and in the absence of further digits, HLCL combined with the base DID number.
D Channel Monitoring:
Monitoring D Channel traffic with LD 96 can be a very useful diagnostic tool for checking incoming/outgoing digit patterns for DID calls. See also D-Channel Monitoring for more details.
Use the following commands in LD 96:
|ENL MSGI x||- enable monitoring of incoming messages|
|ENL MSGO x||- enable monitoring of outgoing messages|
|DIS MSGI x||- disable monitoring of incoming messages|
|DIS MSGO x||- disable monitoring of outgoing messages|
|STAT MON x||- display the monitoring status of one or all D-channels.|

- During high traffic some of the monitored messages may be lost.
- For the D-Channel monitor messages to be displayed, the TTY must have USER MTC in LD 17.
- D-Channel message monitoring can produce a lot of TTY output, so remember to disable when no longer required!
