Advanced Installation and Programming
3. In Form 04, System Options/System Timers, enable option 86, PRI
Card - QSIG, to allow Calling Name and Number to be transmitted
over IP trunks.
4. In Form 13, Trunk Circuit Descriptors
- Set a descriptor to T1 E&M in the Options subform. Descriptor 7 in
the default database has the correct settings for IP trunks. If
selecting another descriptor, set options to the default values,
except:
set Incoming Start Type to WINK
set Outgoing Start Type to WINK
set QSIG Supplementary Services to YES
set DTMF to NO.
5. Form 15, Dial-in Trunks
- In the CDN field, enter the descriptor number that defines the T1
E&M trunk specified in Form 13.
6. Form 16, Trunk Groups
- All IP Trunks must be programmed in the same group. To avoid
collisions with incoming IP trunk calls, enter the trunks into the
group in the opposite order that the far end has them entered.
7. Form 23, Route Definition
- Program route definitions
- In the Show IP subform, specify the routes of IP Trunk Groups.
8. If the connection to the PSTN is through embedded PRI (Dual T1/E1
Framer or T1/E1 Combo module), program Calling Party Number
(CPN) substitution in the following Forms
- Form 54, Calling Party Number
- Form 19, Call Rerouting Table
- Form 22, ARS: Modified Digit Table
9. If you have not already done so, program the following Forms:
- Form 26, ARS: Digit Strings.
- Form 22, ARS: Modified Digit Table.
Note: In Form 22, for all SX-200 ICP controllers in the network, program a
modified digit entry with CPN enabled for external calls (calls destined to the
PSTN through the embedded PRI). Program another entry with CPN disabled
for internal network calls.
