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.”
