I have been given responsibility on a pair of Elite 192's is there some place I can download or otherwize get the Hardware guide, specifically something that tells me what does what on the amphonal connectors, 2nd how to tell what software version I am on, I know the system itself is approx 9-10 years old

The Amphonal's Start From The Back to Front,Depending on the card in a Given Slot,It will Pinout 3 Slots.Try the Manuals Tab above, The book should be easy to find.To find out CPU Ver. From any phone, press Feature+3

I looked at the system and here is what is in the slots, going from right to left
s8 empty
s7 SLI8-u10
s6 SLI8-u10
S5 SLI8-u10
S4 ESI8-u10
S3 COI4-u10
S2 CCH(4)-U10
S1 DTI-u30
ISA empty
CPU CPUB(550)-u10-ETU
based on this I know the SLI8 is 8 port single line telephone, COI4 is 4 incoming loop start lines ESI8 means 8 digital phones, I'm a little confused on the S1 & S2 slots,
I looked in the manual section and didn't specifically see the 192 listed anywhere,

DTI is For T-1 (PRI), CCH is Common Channel Handeler.Those two card's will not be needed if your going to put copper Lines on the System.Just your ESI8 and COI. Google the book Its out there since the 192 has been discontinued.

Please do not link to other sites. Thank you.


The 192 is Basicly like IPK.

The DTI & CCH work in tandem with each other for K-CCIS. The DTI is the interface to the T-1 & the CCH is the Common Channel Handler. The DTI will only support T-1 not PRI.

thanks to all, I have since found the hardware manual which answered lots of questions, the only thing I have that is still pending is the voltage/amperage of the larger batteries on the lower left side, I'm suspecting they have not been changed ever,

Ours uses two (2) 12V - 2.6Ah

Number PX1202W.

and since I have a pair of 192's I will need a 4 batteries,
