Explanation:
1) T1 or E1 with CAS or PRI: PBX to PBX2) FXO: off-net3) FXS: local4) FXS or

switcH. on-net5) E&M, FXO, FXS: PLAR

PBX to PBX connections can use T1 or E1 with CAS or PRI: PBX can connect to a network
through T1 or E1 lines with channel associated signaling (CAS) or Primary Rate Interface (PRI)
signaling.
For off-net calls, the typical connection between the router and the PSTN is through FXO port.
A local call just needs FXS ports so it is the only choice for this type of call.
We can make on-net calls through FXS port (phone directly connected to the router) or FXO port
(phone connected to a PBX). The “switch” here means that we can connect an IP phone through a
switch and place on-net calls through Cisco Unified Communications Manager.
A PLAR call can work with any type of signaling, including E&M, FXO, FXS interfaces.
