Function expansions with options bus

Function expansions can be connected to the O-bus (options bus) interface as required. No
major hardware adaptations are necessary. The central processor recognises the connected
modules when the system is booted and supplies them with the requisite parameters for initial-
isation. All modules are of the plug-in type. Up to four of a given module can be inserted (ex-
ception: only one STRB), or different modules can be combined as required.
3.6.1

Options adapter

The options bus adapter (OPA) is a mechanical and electrical adapter between the first options
module and the system motherboard.
3.6.2

GEE module

There are 4 call metering receivers in each of the modules listed below. These receivers regis-
ter the call charge pulses and perform initial processing functions:
Module Frequency
GEE 12 12kHz
GEE 16 16kHz
GEE 16 16kHz
GEE 50 50Hz
Table 3-18 GEE module, national versions
The channel for call charge recognition is looped into the trunk and then routed to the TLA.
