Ls-Id Delay Option - AT&T MERLIN LEGEND Release 3.1 System Planning Manual

Identifying Line/Trunk Jacks
NOTES:
1. You cannot mix T1 and Primary Rate Interface (PRI) service on the same
100D module. Any of the following AT&T Switched Network (ASN) Services
can be provided through a T1 or PRI facility: Megacom WATS, Megacom
800, Software Defined Network (SDN), and MultiQuest . PRI also supports
Call-by-Call Service Selection and some ACCUNET switched digital
services. T1 supports Shared Access for Switched Services (SASS) and
ACCUNET Switched Digital Service (or other circuit-switched data service) at
56-kbps. Both support Dialed Number Identification Service (DNIS).
2. The MERLIN LEGEND Communications System supports Centrex service
with loop-start lines only. The system does not support a timed switchhook
flash with ground-start trunks or ground-start emulation on DS1 facilities in
any mode of operation (Hybrid/PBX, Key, or Behind Switch).
3. The MERLIN LEGEND Communications System does not support timed
switchhook flash with NI-1 BRI lines. Pressing the Recall button on a MERLIN
LEGEND telephone will be ignored. If the Recall button is stored as part of an
Auto Dial string, it will not be sent out over an NI-1 BRI line, or stored for Last
Number Dial or Saved Number Dial when calling on an NI-1 BRI line.
4. The MERLIN LEGEND Communications System does not support BRI
features such as Local Area Signaling Services (LASS), CO Transfer, and
other Centrex offerings.
5. Trunks used for incoming caller line identification (ICLID) service should not
have any equipment other than the MERLIN LEGEND line port connected to
them. Connecting other equipment (such as alarms, autodialers, and so on)
may result in distorted or lost ICLID data.

LS-ID Delay Option

The LS-ID Delay option is available through the 800 GS/LS-ID module and is
programmed for each trunk. It prevents applications and adjuncts from
answering before the Caller ID information is processed.
Use the LS-ID Delay option only if the following conditions apply:
If the adjunct or application cannot be programmed to answer on the
second or later ring, (see the documentation for the adjunct or
application).
If the first option applies (as with headsets using Auto Answer All) and
line buttons receiving Caller ID cannot be programmed for Delay Ring,
for example, auto attendants.
NOTES:
1. It is recommended that trunks with the LS-ID Delay option be used as
incoming trunks only.
2. If no delay is programmed, the caller may hear one or two extra bursts of
ringback while the person receiving the call has not yet heard a ring.
