Provisioning the Switch
Provisioning the switch for T1/PRI access
Four-state A-bit signaling, four-state B-bit signaling, and pulse dialing are not supported.
However, lines using these types of signaling are passed through transparently when the MAX
performs drop-and-insert between lines #1 and #2.
(For further information about wink-start and inband-signaling, see the description of the Rob
Ctl parameter in the Reference Guide for your MAX.)
Provisioning the switch for T1/PRI access
Request the following information from your WAN provider about your WAN interface:
• Whether the line uses inband or ISDN D-channel signaling.
• 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 provisioning.
• The D-channel assignment.
• The NFAS ID number (if the T1/PRI line is provisioned for NFAS).
Keep the following additional information in mind:
• In general, ESF framing and B8ZS line encoding are both recommended for T1/PRI-based
applications. In addition, channel 24 must be the D channel, except for applications using
Non-Facility Associated Signaling (NFAS).
• Applications that require NFAS must be connected to an AT&T or Northern Telecom
switch provisioned with NFAS.
The service provider supplies guidelines for NFAS ID assignments and D-channel
assignments. Note that the MAX must have D-channel signaling functionality and at least
two WAN ports to use NFAS.
• The MAX can receive multichannel calls using Combinet or 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.
Switched data Required.
No voice/digital loss plan is allowed, but the
drop-and-insert channels to a PBX and the
channels to digital modems can be voice
channels.
