MG-T1(SIP) [SCA-24DTIA]
16.1.5 Service Conditions
1. MG-T1(SIP) [SCA-24DTIA] is available for North America.
2. Assign the following system data to use MG-T1(SIP):
- ASYDL, SYS 1, INDEX880, bit3=1 (Internal PHE is valid)
- ASYDL, SYS 1, INDEX885, bit7=1 (SP Implementation is valid)
3. MG-T1(SIP) requests registration to SP-PHI.
4. Allocate the mounting location of Internal PHE and MPH/SP-PHI respectively by ALIDL command.
5. One MG-T1(SIP) occupies four groups (1HW) of virtual speech channel. One HW can only be used as
virtual speech channels of MG-T1(SIP) even when only one channel is assigned.
The virtual speech channel of MG-T1(SIP) cannot coexist in the same HW with the virtual speech channel
of other type of MG devices.
6. Virtual speech channels of MG-T1(SIP) cannot be allocated to 24 or later part of Groups in the system.
7. When changing trunk data by ATRK command during MG-T1(SIP) is in operation, the channels on the
corresponding trunk must be once deleted and reassigned by AMGIL command. So communication is dis-
connected on the corresponding channels while data changing.
8. The table below shows the supported signaling format on T1 interface:
Note that the following types of connection are NOT supported.
- FXO Loop Start
- DID Immediate Start/Delay Start
- TIE
- CAMA
9. MG-T1(SIP) does not comply with ANI, E911, and MFC.
10. Supported pulsing signal is PB only.
11. Assign the route number (RT) of MG-T1(SIP) separating from the route number assigned for PA-PRTC
(1.5M DTI) circuit card.
12. Virtual sender and virtual register are used for the incoming/outgoing calls via MG-T1(SIP). A maximum
of 64 sender and 64 register trunks can be used per LP at the same time.
13. [S-127D] Serial Call - D is not supported for the incoming calls via MG-T1(SIP).
