Specify line configuration

If you are working through the Add a new Individual Line task, this step is not required. You can click on the step if you need to see the configuration details, but you cannot make any changes. The Next pushbutton skips past this step because no changes are required. For other tasks, this step is mandatory if you are adding a new Individual Line; it is optional if you are updating an existing one.

Enter the following optional information.


Parameter

Description
Line usage Specifies whether the subscriber intends to use this line for voice, fax and/or modem calls, or exclusively for fax and modem. This controls the use of data encoding and compression on the line. Note that support for T.38 fax encoding depends on the Remote Media Gateway Model being used, and on the T.38 support setting in the Call Agent. This field appears only if Number status is set to Normal, Ported to, or Non-geographic. Values:
  • Voice and fax
    Use this setting if the line can be used for voice calls. The line normally uses 32kbps ADPCM compression (G.726), which is appropriate for voice lines. On detecting a fax tone, it switches automatically to T.38 fax encoding if this is supported, or to uncompressed 64kbps PCM (G.711) otherwise; on detecting a modem tone, it switches to G.711.
  • Fax only
    Use this setting only if the line is used exclusively for fax or modem calls. The line uses uncompressed 64kbps PCM (G.711), but switches to T.38 fax encoding for fax calls if this is supported. Note that G.711 does not provide echo suppression, so there may be problems with echo if the line is used for voice calls.
Signal function code The subscriber's signal function code which is used for CAS signaling. This field appears only if Call Agent signaling type is set to Analog line/T1 CAS and Number status is set to Normal, Ported to, or Non-geographic. Values:
  • Loop start
  • Ground start
  • E and M wink start
  • E and M wink start (Originating), delay start (Terminating)
  • E and M wink start (Originating only)
  • E and M immediate start (Originating only)
  • E and M wink start (Terminating only)
  • E and M delay start (Terminating only)
  • LRB wink start
    The abbreviation LRB indicates Loop Reverse Battery.
  • LRB wink start (Originating only)
  • LRB wink start (Terminating only)
  • Reversed LRB wink start (Originating only)
  • LRB delay start (Terminating only)
  • LRB wink start (Originating), delay start (Terminating)
FSK format The type of FSK tones used to pass Caller ID messages to this subscriber. This field appears only if Call Agent signaling type is set to Analog line/T1 CAS and Number status is set to Normal, Ported to, or Non-geographic, and does not appear if the subscriber uses an access device on a Subscriber Gateway. Values:
  • UK
    Standard UK format
  • Bellcore
    Standard North American format
Line side answer supervision supported Specifies whether Line Side Answer Supervision is supported for this subscriber. This field appears only if Call Agent signaling type is set to Analog line/T1 CAS and Number status is set to Normal, Ported to, or Non-geographic. Values:
  • True
  • False
ISDN default bearer capabilities This field is valid only in the US.
Digit masking required Flag set to indicate that this subscriber's line requires digit masking. Values:
  • True
