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:
|
Nailed-up connection | This field appears only if Call Agent signaling type is set to Analog line/T1 CAS and the configured Access Device uses a GR-303 IDT.
An IDT may be set up so that there are more subscribers than available DS0s within the IDT's Interface Group, so it is possible that a subscriber will be unable to make a call if other subscribers are already using all of the DS0s. Nailing up the connection for a specific subscriber gives priority by ensuring that a DS0 is always reserved for this subscriber's use (except when the configuration prevents the subscriber from making or receiving calls, or when there is a shortage of DS0s because of a failure). In order for this to work, the number of subscribers with nailed-up connections must be smaller than the number of DS0s available in the Interface Group. Values:
|
GR-303 dial type | This field appears only if Call Agent signaling type is set to Analog line/T1 CAS, Signal function code is set to Loop start or Ground start, and the configured Access Device uses a GR-303 IDT. Choose whether the subscriber line supports DTMF dialing in addition to pulse dialing. Values:
|
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:
|
FSK format | The type of FSK tones used to pass Caller ID and Visual Message Waiting Indicator 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:
|
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:
|
ISDN default bearer capabilities | This field appears only if the Call Agent signaling type field is set to ISDN PRI; it is not valid for a Business Group Line. |
