ESCRIPTION
The Protocol to be followed defines the type of interface expected based upon the
equipment type at the distant end of the connection.
Possible values: National ISDN, ETSI, TTC, National ISDN Nortel or Q-Sig
(default = None)
Primary ISDN needs to have Trunk Group assignments to process the calls being
received. If multiple trunk groups are used within the Channel Group, then Call-by-
Call Services must be used.
Possible values: 0~32 (CTX100), 0~48 (CTX670 Basic), 0~128 (CTX670 Exp),
(default = 0)
Primary ISDN needs to have Trunk Group assignments to process the calls being
originated. If multiple trunk groups are used within the Channel Group, then Call-
by-Call Services must be used.
Possible values: 0~32 (CTX100), 0~48 (CTX670 Basic), 0~128 (CTX670 Exp),
(default = 0)
Identify whether the communication with the PSTN requires an identifier. Select
Explicit to require an identifier.
Possible values: Implicit (default) or Explicit
An identifier must be used as part of the addressing when an "explicit" identified is
used to communicate with the PSTN which channel on which link is used for the
given call. This identifier is assigned by the connected PSTN.
Possible values: 0 ~ 126 (default = 0)
PRI includes a 64-kbps D-channel (for transfer of signal information). Select the
channel position to be used for D channel signaling.
Note This field is used only when the span interface speed is 1.5M. If the span
interface speed is 2M the value is fixed at 16.
Possible values: 1 ~ 24 (default = 24)
1. Enable the Bearer Capabilities allowed for this PRI Trunk channel group.
Possible values: Enable (default) or Disable
2. Select the Channel Method (map) to identify the channels.
Note In North America, only Channel Number map is used (Channel Number).
See Table 6-8.
Possible values: Channel Number (default) or Slot Number
1. The Bearer Capabilities (384k Unrestricted(H0), 1536k Unrestricted(H11),
1920k Unrestricted, Restricted Digital Info, Trunk Video, and Unrestricted
Multirate) are not used and should remain disabled.
Possible values: Enable or Disable (default)
2. Select the Channel Method (map) to identify the channels.
Note In North America, only Channel Number B map is used. See
Possible values: Channel Number B (default), Channel Number H, Slot Map B or
