Provisioning the Switch
This appendix provides the information necessary for properly provisioning a switch for T1/EI or T1/E1 PRI access to the WAN. This appendix contains these sections
:
Provisioning the switch for T1 access
If you use an inband signalling line, the T1 circuit at the Point-of-Presence (POP) must support the translations listed in Table A-1 for compatibility with the MAX TNT.
Four-state A bit signalling, four-state B bit signalling, and pulse dialing are not supported.
What you need from your T1 service provider
Request the following information from your WAN provider about your T1 interface:
- Whether the line uses inband or ISDN D-channel signalling
- Whether the line uses B8ZS or AMI line encoding
- Whether the line uses ESF or D4 framing
- Each phone number assigned to the line on a channel-by-channel or service-by-service basis
- The number of nailed-up channels, if any
- The number of unused channels, if any
- The types of call-by-call services (also called NSF identifiers) on the switched channels
- Whether the line uses B channel, H0 channel, or H11 channel, or multirate provisioning
- The D-channel assignment
- The NFAS ID number (if the T1 PRI line is provisioned for NFAS)
Keep this additional information in mind:
What you need from your E1 service provider
Request the following information from your WAN provider about your E1 interface:
- The phone numbers assigned to your E1 interface, channel-by-channel
- Nailed-up channels (also called private WAN), if any
- Unused channels, if any
- Switch type (or emulation)-DPNSS only
- Switch layers 2 and 3 configuration-DASS 2 and DPNSS only (A/B end, X/Y end)
- Rate adaption protocol-DASS 2 and DPNSS only (X.30)
Note: The MAX TNT can receive multichannel calls using MP encapsulation only if all
channels of the call share a common phone number (namely, a hunt group). You can request
that your service provider supply you with a hunt group.
