MERLIN LEGEND Communications System Release 7.0
Feature Reference 555-670-110
Features
Primary Rate Interface (PRI) and T1
Outgoing Only. Only outgoing calls can be made.
Incoming Only. Calls can be received only.
Trunk Seizure Type. The trunk seizure type can be one of four settings. The
setting should be compatible with the signaling on the far end. The trunk seizure
type must be set separately for incoming (intype) and outgoing (outtype) calls.
The intype and outtype settings for the trunk seizure type can be programmed as
one of the following settings:
Wink Start (factory setting)
Delay Start (In networked Release 6.0 and later systems, use this setting
for tandem tie trunks.)
Automatic Start
Immediate Dial
NOTES:
Dial Mode. The dial mode must be set for incoming calls (inmode) and outgoing
calls (outmode). The dial mode (inmode or outmode) can be set to either Rotary
(factory setting) or Touch-Tone. Touch-tone receivers are required on the remote
communications system when the setting is touch-tone. In networked Release 6.0
and later systems, use this setting for tandem tie trunks.
Dial Tone. The dial tone can be set to one of the following settings:
Remote (factory setting). The system sends dial tone to callers.
Local. The system does not send dial tone to callers.
Answer Supervision Timing. Answer Supervision Timing sets a limit in
milliseconds that an answer supervision signal must be present to be considered
valid. The timing can be set to any value in increments of 20 ms from 20 to 4,800
ms. The factory setting is 300 ms, which should be used in networked Release 6.0
and later systems for tandem tie trunks.
Disconnect Timing. Disconnect Timing sets a time limit, in milliseconds, that a
disconnect signal must be present to be considered valid. The timing can be set to
any value from 140 to 4,800 ms, in increments of 20 ms. The factory setting is
300 ms, which should be used in networked Release 6.0 and later systems for
tandem tie trunks.
The Immediate Dial setting should not be used for DS1 Switched 56
data calls because of the lack of trunk integrity-checking. Auto Route by
Line Appearance works only with Immediate Dial and therefore cannot
be used with DS1 Switched 56 data calls.
Automatic-start trunk seizure is not available on 5ESS and DMS-100
central office switches.
