Using Contact Closure In Sls Mode - Avaya G250 Administration

Configuring Standard Local Survivability (SLS)
3. You can either:
Wait for the third party to answer and announce the call, then hang up.
●
Transfer the call before the third party answers by hanging up.
●
The person you were talking to is transferred to the third party.
A message appears on your phone display to indicate that the call transfer was completed.
If the necessary call processing resources are not available, the transfer does not
complete and the event is logged.
Note:
Displays are not supported on analog phones unless they are supported locally

by an analog phone.

Using Contact Closure in SLS mode

When the media gateway is in survivable mode, Contact Closure works as follows:
1. Lift the phone receiver and listen for the survivability dial tone.
2. Dial the appropriate Contact Closure FAC (open, close, or pulse) on the phone.
If you dial an invalid FAC code, then SLS plays an intercept tone and terminates the
●
session.
If you dial a valid FAC code, then you will hear a standard dial tone and can proceed to
●
Step 3.
3. Dial the media gateway number (3 digits).
If you enter fewer than 3 digits, then SLS times out and you must restart this procedure
●
from the beginning.
If the media gateway number matches the local media gateway number, then SLS
●
plays a standard dial tone and you can proceed to Step 4.
If the media gateway number does not match the local media gateway number, SLS
●
plays an intercept tone and terminates the session.
4. Dial the Contact Closure code, for example "1" for contact pair #1, and "2" for contact pair
#2.
You will hear stutter tone and then silence confirming these valid codes. If you dial an
invalid Contact Closure number, you will hear an intercept tone.
Contact Closure feature activations appear in the CDR log (see

Note:
If the Contact Closures are set to manual operation, FAC operation will not work

even though the confirmation tone is heard. An event will be logged, however.
