ISDN trunk group
Issue 5 October 2002 959555-233-506
US NI Delayed Calling Name Update
Administrable if, on the System-Parameters Customer-Options screen, the
ISDN-PRI field is
y, and on the Trunk Group screen, the Carrier Medium field is
either
PRI/BRI or ATM, and the Supplementary Service Protocol field is a. This
field provides display updates to the terminating phone for delayed calling party
name provided by the network,
UUI IE Treatment
Specifies whether the user Information Element (IE) is shared.
Wideband Support
Specifies whether Wideband Switching is supported by this trunk group. Valid
entries are
y or n. For ISDN trunk groups containing ISDN-BRI interfaces, the
only valid entry is
n. Otherwise you can administer this field only if the Wideband
Switching field is
y on the System-Parameters Customer-Options screen. If set to
y, the Wideband Support Options page appears. All trunk members must be from
TN464C (or later) circuit packs.
NOTE:
Wideband trunk calls are treated as a single trunk call when Automatic
Circuit Assurance (ACA) measurements are taken. This way, if an ACA
referral call is generated (for short or long holding time), the wideband call
only triggers a single referral call using the lowest B-channel trunk member
associated with the wideband channel.
