Cisco Bts 10200 Originating Test Line - Cisco BTS 10200 Troubleshooting Manual

PSTN Trunk Testing
The Cisco BTS 10200 supports OTL and TTL capability. User provided test equipment and, optionally,
test controllers may be connected to the test lines. Interoperability between different carriers is ensured
through proper selection of test equipment and test functions.
For the purposes of PSTN trunk testing, the near end is the Cisco BTS 10200 platform.

Cisco BTS 10200 Originating Test Line

This section discusses the following Cisco BTS 10200 originating test line information:
•
•
•
•
•
•
Function
The OTL originates all test calls. The OTL may be part of an automated trunk test system (for example,
CAROT) that will select trunks, make test calls, conduct tests, record measurements and report marginal
or inferior trunk performance.
Test Equipment
Test equipment capable of seizing the test line, outpulsing digits (preferably MF format), recognizing
supervision, and supporting 1XX tests. While Cisco does not recommend any vendor, SAGE Instruments
930 or 935 series test equipment with the proper options are examples for use.
Test Line
Many gateway products can satisfy the OTL requirements. Preferred capabilities include
•
•
•
Trunk Access
The Cisco BTS 10200 OTL can logically access up to 9,999 trunk groups, each with up to 9,999 trunks.
Conditions for trunk test access are met when either the requested trunk is in service and idle or the
requested trunk is out of service or blocked. Trunk access is denied when the requested trunk is busy. If
that happens, route advance is inhibited, and an announcement is returned.

T1 access line to connect to the test equipment to minimize transmission impairments caused by
codecs and analog filters.
Preferred signaling arrangement is wink start with MF signaling. (Other signaling arrangements can
be supported).
