Configuring R2 interregister signaling
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter E1/T1 interface view. | controller { e1 | t1 } slot-number | N/A |
3. Create a TS set and enable R2 signaling for it. | timeslot-set ts-set-number timeslot-list timeslots-list signal r2 | N/A |
4. Enter R2 CAS view. | cas ts-set-number | N/A |
5. Enable the terminating side to request calling party information. | ani { all | ka } | Optional. Disabled by default. |
6. Set the range for the number of calling number digits to be collected. | ani-collected min min-value max max-value | Optional. By default, no restriction is placed on the number of calling number digits to be collected. |
7. Configure the number of digits that should be collected to request a calling party flag. | ani-offset number | Optional. The default for the number argument is 1. |
8. Set the interdigit timeout time in interregister signaling. | ani-timeout timer-length | Optional. 3 seconds by default. |
9. Adopt Group B signals to complete interregister signaling exchange. | group-b enable | Optional. Group B signals are used by default. |
10. Enable this end to send a number terminator to the terminating side. | final-callednum enable | Optional. Disabled by default. |
11. Configure the special characters that are supported during interregister signaling exchange. | special-character character number | Optional. No special character is configured by default. |
12. Configure register signal values in R2 signaling. | register-value { billingcategory | callcreate-in-groupa | callingcategory | congestion | demand-refused | digit-end | nullnum | req-billingcategory | req-callednum-and-switchgroupa | req-callingcategory | req- currentcallednum-in-groupc | req-currentdigit | req- firstcallednum-in-groupc | req-firstcallingnum | req-firstdigit | req-lastfirstdigit | req-lastseconddigit | req-lastthirddigit | req-nextcallednum | req-nextcallingnum | req-switch-groupb | subscriber-abnormal |subscriber-busy | subscriber-charge |subscriber-idle } value | Optional. The defaults vary by country mode. |
13. Configure the duration of register pulse signals such as A-3, A-4, and A-6 in R2 signaling. | timer register-pulse persistence time | Optional. The default is 150 milliseconds. |
14. Configure the maximum time waiting for a Group B signal. | timer register-complete group-b time | Optional. The default is 30,000 milliseconds. |
