CT Bus Interface
752i supports an optional computer telephony (CT) bus interface that routes 
various signals from the CompactPCI J4 backplane connector to the PCI Telecom Mezza-
nine Card (PTMC) expansion sites. The Katana
752i complies with Configuration 2 of the 
PCI Telecom Mezzanine/Carrier Card Specification, PICMG 2.15.
Note:
752i configuration does not support any of the CT bus interface options.
PICMG 2.15 CONFIGURATION 2
PTMC mezzanine and carrier cards supporting PICMG 2.15 Configuration 2 are identified as 
PT2MC and PT2CC. This configuration includes a Time Division Multiplexed (TDM) inter-
face, a Reduced Media Independent Interface (RMII), and a TTL serial port.
There are several compatibility types between combinations of a carrier card and a mezza-
nine card. Although PTMC and PTCC are mechanically compatible with each other, the PMC 
mezzanine or carrier cards electrical compatibility is partially determined via PCI Telecom 
Identifiers (PTIDs) and enable (PTENB*) signals. The Katana
752i compares the PTID to 
configurations that it supports and activates PTENB* after determining compatibility is 
acceptable. At power-up, PTENB* is inactive and will activate once electrical compatibility 
is determined via the PTIDs. 
Another method to determine compatibility is interoperabilty. There are three interopera-
bilty categories for combining mezzanine and carrier cards, per PICMG 2.15: 
Fully Interoperable Combination (FIC)
FIC indicates combinations that do not limit functionality and are never a destructive com-
bination. The Emerson Katana
752i (PT2CC) and 
PM/3Gv (or other PT2MCs) are a fully interoperable combination. 
Non-Destructive Combination (NDC)
NDC indicates combinations that are not intended to interoperate, but will not cause dam-
age to either the carrier or mezzanine card. For example, combining a PT2MC and a PT4CC 
is an NDC.
