FEATURES AND SERVICES
Third-Party Call Setup
A data terminal (on System 25) or workstation (on the STARLAN NETWORK) can set up a
call between two other stations (voice or data) using the Third-Party Call Setup feature.
Since voice port/data port associations are not meaningful for STARLAN CP ports,
STARLAN NETWORK workstations must always specify the Personal Dial Code of the
source voice terminal or the Data Dial Code of the source data terminal. Note that this
feature can only be administered for the STARLAN CP ports as a group, and not for
individual STARLAN NETWORK workstations.
When placing voice calls using CAM, Third-Party Call Setup is used automatically.
Wiring
The STARLAN NETWORK wiring plan is based on standard 4-pair building wiring. The
STARLAN NETWORK uses two pairs of the 4-pair cable, allowing the remaining two pairs to
be used for voice service.
STARLAN NETWORK data is transmitted over pairs two and
three. Figures 2-46 and 2-47 provide typical connection information.
A Y-adapter may be used to combine/split the pairs at the System 25 cross-connect field.
STARLAN NETWORK NAUs provide an RJ11 phone jack that terminates pair 1. Single line
sets may be plugged directly into this jack (Figure 2-46). MERLIN Communications System
sets require an ATL adapter and local power (Figure 2-47).
ATL Adapters
The ATL adapter (KS23475) is a connection block that provides: 48V dc power from T1 (via
modular cords C4 and C1) to the ATL phone, data connections from the STARLAN
workstation, and phone connections from the ATL phone (via modular cord C1) over a
shared common cable (C3) to System 25. The phone and data connections are on separate
wire pairs that are split-out at the SIP “Y” adapter (A1). Phone wiring is cabled to the ATL
Line CP (ZTN79) by octopus cable C2, and data wiring is cabled to the NEU by modular cord
C1.
Administration Requirements
The STARLAN CP is administered as a type of data port. Some items administered on one
port are automatically administered for all four ports on the CP, others are individually
administrable.
Individually Administrable (default):
● DDC of port
● DDC to hunt to next (none)
● Display ID
