Analog Junctors / Channels 
3.12 If analog bays are present in an SX-2OOe system, the analog 
cards are connected to 32 junctors, or voice paths via analog 
crosspoint chips. These are located on the cards themselves, and are 
in turn connected to the 32 channels of the bay’s digital link via the 
Digital Interface Card. Refer to Section MITL9108-093-180-NA, En- 
gineering Information for further details on this interface. Chart 3-10 
outlines the troubleshooting procedures for the analog junctors..

Attendant Console 
3.13 The Attendant console is a microprocessor-controlled liquid 
crystal display terminal which integrates access to the SX-200’ 
DIGITAL PABX system data and telephony functions in a single device. 
it is adaptable to many different applications, including Maintenance 
and Customer Data Entry. Chart 3-11 shows the steps involved in the 
troubleshooting of the Attendant console. 
Further information on the Attendant console may be found in Section
