IPECS Release 5
Feature Description & Operation 5.0
2-137
iPECS supports two (2) standard protocols, QSIG over ISDN and H.450 over IP, for the basic
networking functions and the proprietary iPECS protocol for the advanced networking features.
QSIG employs ISDN PRI channels only with support for ESTI standards ETS 300-
237/238/256/257/260/261/361/362/363/364.
Operation
Operation of Distributed Networking is automatic when configured & defined
Conditions
1. To use the networking features, the software lock-key installation is required. Two types of
software lock-key relate to the networking protocols. One is for QSIG based networking
protocol, and another is for VOIP based networking protocol. Each iPECS system has a
unique software lock-key. To get the software lock-key, contact the distributor of iPECS system.
2. Unified Dialing Plan (UDP): Each station can have a unique number up to 7 digits in the
networked systems, but it depends on their own numbering plan.
3. The alternative route employs a Speed Dial number to place a call and is not a Networked call.
Thus, the Distributed Control Network features are not available.

Description
A station user can make a call to a station in other systems by dialing only a station number just as
an intercom call within the same system.
Operation
1. Lift Handset or press the [
SPEAKER] button. The system provides a user with a dial tone.
2. Dial the station number of other systems, or press the {NET DSS} button of other systems.
3. The station seizes the network CO line according to the net routing table, and the system sends
a digit stream that is modified by the net routing table.
4. The called party receives a digit stream that is sent by calling party, and analyzes it using the
net routing table to determine
5. The right destination. The called station receives a ringing signal.
6. The LED of [Network CO] button will be extinguished when the Net Call is cleared.
Conditions
1. Net call must be used without seizing a CO line.
2. User hears an error tone if there is no idle networking path.
