Features
Feature
Voice Ports
Two or Four FXS ports
Connects to a telephone or fax, or to a
PBX or key set that emulates a telephone.
Uses RJ-11 connectors.
Note: The end-to-end connection between
the CO RJ11 jack and the router voice-port
must be a straight-through connection.
Connections
This means that TIP goes to TIP and RING
to RING. Normally the CO provides an
interface for which a standard rolled RJ11
cable can be used since the connection that
results is straight. However, sometimes the
CO cannot reverse the pinouts and
therefore, a straight RJ11 cable is needed.
