Hello Fellow Techs,
We are trying to Certify and Inventory a Telrad Digital Bx. We are not familiar with this switch
The System has 10 incoming lines that hunt. They have, at their site 7 Digital(79-100-000) sets
In the slot-carrier the circuit packs are as follows:
MPD (red) assuming this is a type of processor Card
COL (blue) circuit pack
OCD (yellow) circuit pack
ELD (green) circuit pack
Can anyone please tell the Circuit Description of these cards,please?
Is thers a way I can go the the ADMIN. set and identify the type of software
Thank you for your help

MPD is a 818 processor, look for the Memory Cartridge on the MPD to find the software level. You will need the software level if you want to buy a programming kit to be able to make changes to the programming.
COL is a 8 port loop start line card
OCD is a options card it will also have modules mounted on it MIM, Modem, DTMF. Dont think you will have a DTMF with out a T1, Modem you should know MIM is voice channels for external page to voicemail
ELD is a 8 port dual audio station card. Most times used to power 16 single audio path phones.
