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 Notic es

).
Install System Access Ports
1. Before connecting various endpoints that use EIA interfaces to the system,
install up to 8 loop-around c onnections for Mode 2-to-Mod e 3 (and vice
versa) data conversion.
From the

outgoing

perspective of the system c ommunicating with an EIA
endpoint, these loop-around connections convert Mod e 3 data (circuit-switc hed
packet data, with und efined bit rates and p acket specifications) to Mod e 2 data
(low-speed, usually asynchrono us, data at rates of 300 to 19,200 bps) b y:
■Accepting Mode 3 data off the LAN bus (from the SPE) at a TN553 Packet
Data Line circuit pac k, where Mode 3-to-Mode 2 conversion is d one
■Routing the converted data throug h the cross-connect field and back to a
TN726B Data Line where the equivalent Mode 2 d ata 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 incl ude:
■Generic 3 Management App lications (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)
