Port Expansion Unit (Peu); Peu 205; Peu 200 - Telecor VS1 Installation, Configuration & Operating Manual

Port Expansion Unit (PEU)

Each VS1 business telephone system requires one or more Port Expansion Units (PEUs) to which
all standard CO lines and station equipment are connected. Each PEU has 16 RJ-11 ports.
The first PEU is attached to the Telecor Voice Server (TVS). An additional PEU can be daisy-
chained off the first PEU. The TVS comes with a 32-port Host Adapter Card from which a
maximum of two PEUs can be daisy-chained. To connect additional PEUs to the TVS, you must
install additional Host Adapter Cards.

TVS for a total of 192 ports.
Three PEU models are available as described below:
PEU 250
The Port Expansion Unit Model 250 (PV-PEU-250) contains 16 generic ports that you can
configure as CO or station ports. Ports are configured using pushbutton switches located next to
each port jack. Eighteen dual-color LEDs (amber and green) on the front of the PV-PEU-250
indicate power and communication status. The PV-PEU-250 includes integrated caller ID circuitry
on all 16 ports. Automatic cut-over is provided for ports 1 through 4 if the ports are configured as
CO ports. If a power failure occurs, the ports cut over to ports 5 through 8 respectively, if ports 5
through 8 are configured as extensions. The PV-PEU-250 can be used as any PEU in a system. It
does not contain external device contacts. External devices are connected to TVS via the Dry
Contact Unit Model 100 (PV-DCU-100).
Note If your current TVS software version is prior to 2.9, only the first eight ports on the Model
250 are configurable as CO lines.

PEU 205

The Port Expansion Unit Model 205 (PV-PEU-205) contains six external device contacts including
two zone pager outputs for overhead paging systems, two music inputs for music on-hold or
promotions on-hold, and two dry contact relays to attach electronic door locks, buzzers, or sirens.
The Model 205 typically serves as the first PEU on a system with Model 200 PEUs connected as the
second and additional PEUs. Of the 16 ports the first eight ports can be configured as CO ports or
station ports. The remaining eight ports can be configured as station ports only.

PEU 200

The Port Expansion Unit Model 200 (PV-PEU-200) has all the same features of the Model 205 but
it does not have the six external device contacts. The Model 200 typically serves as the second, and
additional PEU on systems using the Model 205 PEU as the first PEU. Of the 16 ports, the first
eight ports can be configured as CO ports or station ports. The remaining eight ports can be
configured as station ports only.
