CHAPTER 3<br />
INSTALLING THE SWITCH<br />
Preparing the Site for VDSL/POTS Connections<br />
In multi-tenant buildings, phone lines from the service provider enter the<br />
site and are terminated at a location referred to as the MPOE (Minimum<br />
Point of Entry). The MPOE is the “demarcation” point where the service<br />
provider’s cables end and that of the building’s owner/customer begins.<br />
An MPOE typically consists of two sets of punch-down blocks; one from<br />
the service provider, and the other from the customer. The customer’s<br />
punch-down blocks are connected to PBX or MDF equipment in the<br />
building. A PBX may have either analog or digital cards that provide the<br />
phone lines to individual end users. The PBX lines are usually connected<br />
to the end users through another set of punch-down blocks or patch<br />
panels. The following figure displays the normal wiring before installing<br />
the VDSL switch.<br />
