Euro-Card [Dimensions] Form Factor
The CT [Computer Telephony] Bus is a Telecommunications bus [Telcom bus]
which may be implemented on either a PCI or cPCI card as a sub bus. The CT bus provides a
TDM [Time Division Multiplexing] scheme over PCI and CompactPCI (cPCI)
bus architectures. The TDM bus carries real-time voice and fax traffic
across the TDM bus that implements 4,096 bidirectional time slots (64
Kbits/sec each). The bus can support up to 2,048 full-duplex calls.
H.100 CT Bus is a mezzanine bus used with PCI. The bus works over ribbon cables between
normal PCI cards connected on a PCI bus.
"The CT Bus is a bit-serial, byte oriented, synchronous, TDM transport
bus operating at 8.192MHz. It consists of two clocks, two frame sync
pulses, one backup network timing reference, and 32 independent
bit-serial data streams. Voice/data transfer on the bus is accomplished
by assigning one or more time-slot numbers and bus stream numbers to the
sender and receiver(s). At the selected time-slot, the software-selected
sender drives the bus and somewhere on the bus, the receiver(s) clock in
the data bits.".. "The H.100 specification documents CT Bus Clocks and
Synchronization; data bus lines, interface device requirements, data bus
timing, clock skew, reset, power on, and other timing requirements;
electrical specifications, mechanical specifications including the design
and location of connectors, pin assignments, PCB layouts, and cable
requirements; support for partial implementations and optional signals;
and inter-operation with other buses."
H.110 CT Bus is a bus used with CompactPCI [cPCI]. In this case the H.110 signals
travel over the backplane.
"The H.110 specification is functionally identical to the H.100
specification. However, some of the features in H.100 relating to high
availability realize their full utility only in the hot swap CompactPCI
environment. There are electrical differences between H.100 and H.110 due
to the differences between a ribbon cable and a backplane implementation.
The CT Bus is defined on 6U CompactPCI form factor printed circuit boards
(PCB) and is implemented on the CompactPCI J4/P4 connector. In addition
to the topics covered in the H.100 specification, the H.110 specification
includes detailed hot swap requirements." Quote obtained from H.100 and H.110 CT Bus for PCI and Compact
PCI; ECTF.org

Both the H.100 and H.110 CT Bus use the electrical
requirements defined in the H.100 Specification.
The specification calls for VOL = 0.4v, and VOH =
2.4 volts which are normal TTL levels.

The 6U Euro card size is used with the H.110 specification [using the J4
connector].
Three styles:
Z1 [Zone 1]: Power/Management
Z2 [Zone 2]: Data Interface (which consist of 5 ZD connectors;
each is 4 rows x 10 columns of shielded differential pin pairs)
Z3 [Zone 3]: Rear panel interconnect [Rear Transition Module]
