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/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.)
Provisioning the switch for T1/PRI access
Request the following information from your WAN provider about your WAN interface:
•
Signaling mode (inband or ISDN D channel.
•
Encoding method (B8ZS or AMI).
•
Framing method (ESF or D4 framing).
•
Each telephone number assigned to the line on a channel-by-channel or service-by-service
basis.
•
Number of nailed-up channels, if any.
•
Number of unused channels, if any.
•
Types of call-by-call services (also called NSF identifiers) on the switched channels.
•
Data channel provisioning (B-channel, H0-channel, H11-channel, or H12-channel).
•
D-channel assignment.
•
NFAS ID number (if the T1/PRI line is provisioned for NFAS).
Keep the following additional information in mind:
•
In general, both ESF framing and B8ZS line encoding are 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 telephone number (called 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/insert channels to a PBX and the chan-
nels to digital modems can be voice chan-
nels.
