MultiVoice Gateway for the MAX— User’s Guide
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
MultiVoice Gateway 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 MAX Reference Guide.)
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 MultiVoice Gateway must have D-channel signaling
functionality and at least two WAN ports to use NFAS.
•
The MultiVoice Gateway 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.
What you need from your E1/PRI service provider
You need the following information from your E1/PRI service provider:
•
The phone numbers assigned to your E1/PRI 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)
