Survivable Remote Gateway 50 Configuration Guide
5 Add a destination code.
a Access the Dialing Plan - Routing panel ( Configuration > Telephony > Dialing Plan >
Routing ) and select the Destination Codes tab.
b Add a new destination code.
Use the ALTPrefix as the destination code.
c On the ALTPrefix Destination Code row, select the Normal Route field.
d Enter the route for the Attendant telephone (997).
e In the adjacent Absorbed Length field, select All from the pull-down menu.
When the SRG receives the ALDN digits from the main office, it looks up the destination
code table, finds a match for the ALTPrefix, dumps all the digits (ALDN), and dials the
main office Attendant.
To configure Alternative Call Routing on the SRG50; with DID
trunks
1 Complete the procedure: To configure the SRG50 for NBWM and ADBWM ( “To configure
the SRG50 for NBWM and ADBWM” on page 39 ).
2 Refer to “Call routing: configuring for outgoing calls” on page 86 and the BCM50 Networking
Configuration Guide (N0027156) for more information on the logic behind this procedure.
3 Obtain the ALTPrefix for the SRG50 (configured at the main office).
4 Define a route for the NPA-NXXX portion of the main office DID numbers.
a Access the Dialing Plan - Routing panel ( Configuration > Telephony > Dialing Plan >
Routing ) and select the Routes tab.
b Add a new route (for example, 996).
c Ensure that the DN Type is Public (Unknown) .
d In the External Number field, enter the NPA-NXXX of the DID trunks that serve the
main office.
e Assign the PSTN line pool to the route (select the line pool from the Use Pool pull-down
menu; default is A ).
Note:
In order to support DID trunks, the MODN dialed by an SRG50
caller must match the DID digits.
Note: In the following procedure, it is assumed that the MODN matches
the XXXX portion of the DID’s NPA-NXX-XXXX; and that the
ALTPrefix is 3 digits.
