OFF-PREMISES STATIONS (OPS)

Description

An OPS is a single-line voice terminal that is located in another building and connected to System 25 via arrangements with the local CO. The station has the same features as an on- premises single-line station except that it is counted as an outside party in a conference call. Also, the Message feature will not operate with these sets.

Considerations

This service is sometimes furnished to executives at their residences. It allows them remote access to System 25 features and services.

Interactions

●Conference: For conference purposes, an OPS counts as one of the two allowable outside lines.

●Distinctive Ringing: For V2 systems, Distinctive Ringing is not provided; OPS stations will always receive standard (that is, single) ringing for calls.

Administration Requirements

Single-Line Voice Terminals (Station Port):

●Assign port on Analog Line (TN742) CP

●Make This an Extended Station (Yes/No) - Default = No. (This is how the system knows the station is an OPS.)

Hardware Requirements

Requires a port interface on a TN742 Analog Line CP.

The OPS must be a FCC registered single-line voice terminal.

Connectivity information is provided in Section 4, “Hardware Description.”
