Switch Settings

[Guest Jonah]

I am setting up voiceguide at a new location and the switch programmer has asked me for some information regarding switch programming. Can you please answer the following questions? Thank you.

 

1. Is the frame setting super-frame (SF) or extended super-frame (ESF).

 

2. Is the line coding alternate mark inversion (AMI) or binary eight zeros substitution (B8ZS)

 

3. Is the circuit T1 with channel-associated-signaling (CAS) OR ISDN-PRI with common-channel-signaling (CCS or D-Channel Signaling)

 

4. Is the ISDN switch type National ISDN, 5ESS, or DMS100.

ISDN (PRI with D Channel signalling).

 

ISDN uses B8ZS.

 

 

[Guest Jonah]

what about questions 1 and 4 ?

[SupportTeam]

The preferred ISDN protocol is "National ISDN".

 

Framing must be ESF for ISDN.
