The BTS 10200 supports calls used to test individual trunks that connect a local gateway with a gateway
or PSTN switch at a remote office. The BTS 10200 supports OTL and TTL capability. User-provided test
equipment and, optionally, test controllers can be connected to the test lines. Proper selection of test
equipment and test functions helps to ensure interoperability between different carriers.
The processes described in this section are applicable to the BTS 10200. The processes might work
differently on other switches.
The process for testing a BTS 10200 OTL is as follows:
1.
The user verifies that the remote CO has the desired 1xx test line available.
2.
The user sets up a test device on a CAS TGW that is connected to the local BTS 10200.
3.
The user provisions the CAS-TG-PROFILE table, setting TEST-LINE = YES. (Provisioning
commands are described in the
Cisco BTS 10200 Softswitch CLI Database
)
4.
On the test device at the CAS TGW side, the user enters digits representing the circuit to be tested
and the test to be performed:
–
TG, for example 0003
–
Trunk number, for example 0018
The complete trunk address in this example is 00030018.
–
Test type (10x), for example 104
The technician dials KP-00030018-104-ST.
5.
The BTS 10200 automatically inserts either 9581 or 9591 in front of the test type digits to create a
dialing string.
The complete test string in this example is PREFIX | 00030018 | 9581104 | END.
Note
Alternatively, with the BTS 10200, the user can dial the test type with the 9581 or 9591 included:
KP-00030018-9581104-ST.
6.
The BTS 10200 selects the trunk to be tested based on the user-defined trunk address.
7.
The TGW outpulses the digits to the remote switch over the designated trunk.
