PDATA-PT (Packet Data Line Port)

System Ports and the PDATA Circuit Pack

The Packet Data Line Circuit (PDATA T N553) port board supports the connec tion
of asynchronous EIA RS-232C endpoints to the packet b us. Each PDATA circuit
pack has twelve (12) por ts. PDATA ports are used solely to supp ort the System
Ports feature. System ports provide a means for the SPE to communicate with
data applic ations via the TDM bus, something the SPE cannot otherwise do,
since it has no direct c ircuit-switched ac cess to the TDM bus. Each system port
consists of a PDATA circuit pack port and a Data Line (TN726B) circ uit pack port
which are cross-connec ted at the wall field. The PDATA side of the pair provides
an interface to the Packet Bus for Mode 3 packet data com ing from the SPE via
the Packet Interface circuit p ack. The PDATA converts the Mode 3 packet data
into EIA data which the Data Line circ uit pack then converts to Mode 2 data and
places on the TDM bus. The data stream c an then be directed to any external
application having an EIA interface by routing it throug h another Data Line port
(See the figure below.) System ports allow the following ap plications to
communicate with the SPE:
Save/Restore of Announcement Circuit Pack Recorded Announc ements
Call Detail Recording (CDR)
Journal Printer for the Property Management System (PMS)
Wakeup Log Printer for the Property Management System (PMS)
System Printe r
Data Terminals
Remote G3-MT terminals
Although the paired PDATA and Data Line circuit pac ks used for system ports
may be located ind ependently and in any p ort network, they are usually plac ed
in adjacent slots in the PPN.
