This CPE provides one RJ-45 Ethernet connection and two RJ-11 connectors-one for the wall and one for a telephone. It can be mounted on or under a desk, or on a wall. It ships with a mount lock-in mechanism and clip-on Ethernet cable guard to discourage theft, as well as an Ethernet cord. The Cisco 575 LRE CPE device supports POTS traffic-including ISDN or digital phones-that coexists over the same LRE line by splitting LRE and POTS traffic at the CPE device. A POTS Splitter is required for connectivity to the PBX and LRE switch stack.
