SMC Networks VDSL2 manual Installing the Switch

CHAPTER 3 INSTALLING THE SWITCH

Preparing the Site for VDSL/POTS Connections

In multi-tenant buildings, phone lines from the service provider enter the site and are terminated at a location referred to as the MPOE (Minimum Point of Entry). The MPOE is the “demarcation” point where the service provider’s cables end and that of the building’s owner/customer begins.

An MPOE typically consists of two sets of punch-down blocks; one from the service provider, and the other from the customer. The customer’s punch-down blocks are connected to PBX or MDF equipment in the building. A PBX may have either analog or digital cards that provide the phone lines to individual end users. The PBX lines are usually connected to the end users through another set of punch-down blocks or patch panels. The following figure displays the normal wiring before installing the VDSL switch.
