Verify Usable Circuit Pack Vintages
1. Verify every circuit pack reused in the upgrade conforms to the usable
vintage requirements for a Release 8r system (see
Reference Guide for
Circuit Pack Vintages and Change Notices
).
Install System Access Ports
1. Before connecting various endpoints that use EIA interfaces to the system,
install up to 8 loop-around connections for Mode 2-to-Mode 3 (and vice
versa) data conversion.
From the
outgoing
perspective of the system communicating with an EIA
endpoint, these loop-around connections convert Mode 3 data (circuit-switched
packet data, with undefined bit rates and packet specifications) to Mode 2 data
(low-speed, usually asynchronous, data at rates of 300 to 19,200 bps) by:
■ Accepting Mode 3 data off the LAN bus (from the SPE) at a TN553 Packet
Data Line circuit pack, where Mode 3-to-Mode 2 conversion is done
■ Routing the converted data through the cross-connect field and back to a
TN726B Data Line where the equivalent Mode 2 data can access the TDM
bus, for subsequent routing to an EIA endpoint
The endpoints that use these EIA interfaces and, therefore, require the Mode
2-to-Mode 3 conversion include:
■ Generic 3 Management Applications (G3-MA)
■ Remote Management Terminal
■ Basic Call Management System (BCMS) terminal
■ Call Detail Recording Unit (CDRU)/Centralized Attendant Service Plus
(CAS+)
■ Property Management System (PMS)
■ Printers
