Chapter 11. Dial Plan

DUAL T1/PRI MODULE: NETWORK TERMINATION/PRI

One HDLC resource is used by each PRI or each Packet Endpoint.

When you are working in the network termination section of the DIAL PLAN menu, when SLT is defined as T1/PRI-2, and when SIG is set to PRI, the fol- lowing configuration options are available:

SWITCH TYPE

Write security: 3; Read security: 5

 

 

 

Defines the type of PRI switch to which the port is connected. If connected

 

to another ATLAS 550, both need to be set to the same switch type. The fol-

 

lowing options are available:

 

 

 

Lucent 5E

Northern DMS 100

 

National ISDN

AT&T 4ESS

FIRST DS0

Write security: 3; Read security: 5

 

 

 

Defines to the ATLAS 550 the first DS0 for this endpoint.The ATLAS 550

 

uses DS0s, starting with this selection, to send and receive calls to and from

 

the network (PSTN). The outgoing calls which are allowed or restricted

 

over these DS0s are set by OUT#ACCEPT (see page 11-3) and OUT#REJECT

 

(see page 11-5).

 

 

 

NUMBER OF DS0S

Write security: 3; Read security: 5

 

 

 

Specifies the number of DS0s ATLAS 550 uses for this endpoint.

OUTGOING NUMBER

Write security: 3; Read security: 5

 

 

CONVERSION

Converts outgoing (towards the network) numbers to the selected number-

 

ing plan and type option.

 

 

AS DIALED

Sends the digits provided as an unknown number type.

ISDN-NATIONAL

Regardless of what type of number is received, the outgoing number is sub-

PREFERRED

stituted with ISDN-National as the number plan and type. Ten digits are

 

always sent to the network. Leading ones, if present, are stripped out and

 

the area code (provisioned under DIAL PLAN/GLOBAL PARAMETERS) is

 

added, if only seven digits are supplied. This action may be required in

 

areas with ten-digit local dialing.

 

 

ISDN-

Examines the incoming number and if seven digits are received or if a ten-

SUBSCRIBER

digit number is received with an area code that matches the area code pro-

PREFERRED

visioned in the global parameters, the number is forwarded to the network

 

as a seven-digit number defined as ISDN-Subscriber number plan and type.
