The Pentara trunk port should look just like a standard
telephone terminal, so if the adaptor works with one of
those, it should be OK - except...
Adaptors may not generate enough ring current to trip a PABX
port. The effect is the same as if the port was connected
to a very long exchange line.
On larger PABX systems, the trunk dialling characteristics
(e.g. dial-tone delay, inter-digit pause), can be programmed
to suit the line. If the adaptor doesn't match exactly
the characteristics of a BT analogue exchange line, this
could cause problems.
Multi-line routers are generally intended for PABX
connection, so these are likely to be OK.
