Test Access Ports (TAPs)

Any supported circuit pack in slots 3 through 10 can be provisioned as the TAP
as long as it does not have any existing connections on it. Multiple test access
connections can be established on a TAP as long as the TAP has the bandwidth
available to carry all of the traffic.
The following facilities can be assigned as test access ports are DS1, DS3,
EC1, OC3, OC12, and OC-48. A facility and all its channel is reserved for Test
Access when its secondary state is set to test (TS).
The rates and path types that can be placed under test access are DS1, DS3,
VT1.5, STS1, STS3c, STS12c, STS24c and STS48c.
