TN794  Network Control/Packet Interface for 
si only
The TN794 provides LAPD connections over the TDM bus, as currently provided by the 
Processor Interface (TN765). The TN794 replaces the NETCON (TN777B) and PACCON 
(The TN777B is replaced by the TN794 Network Control/Packet Interface (for R7 and 
later).) in R8 or later si systems. It is not backward compatible with earlier releases. The 
TN794 inserts into the NETCON slot and may require a TN2400 Net/Pkt Backplane 
Connection (R6si and older field upgrades when reusing the existing Control Cabinet 
only). A modified TN790B processor circuit pack and a TN792 DUPINT circuit pack are 
required for duplicated systems.
TN794/TN2400 Sandwich Board Assembly 
The TN794/TN2400 Sandwich Board Assembly (comcode 848254942) is required for 
upgrades to R7si that reuse the existing backplane. The board bridges the packet bus to 
the TN794 NetPkt circuit pack. The TN794/TN2400 Sandwich Board Assembly cannot be 
separated into two circuit packs.
Replaces the TN778 packet-control circuit pack in field-upgraded systems (in new-build 
systems, the TN2400’s function is performed by a revised backplane). Used with the 
TN794.
A new TN790B Processor circuit pack and the new TN792 DUPINT circuit pack are 
required for R7si duplicated systems
TN795 Processor (DEFINITY ONE)
The TN795 processor provides a system offering support for up to 40 voice stations with 
co-resident voice switching, voice and fax messaging and system applications that are 
running on a Microsoft Windows NT operating system.    The communication between the 
firmware and the software is done by an Ethernet connection. An Intel processor 
Message Link or IML is the Ethernet control like between the Pentium processor and the 
MPC860 processor. This allows for the message based communication between the two 
processors.
The TN795 is the equivalent to 2 standard DEFINITY cards but has only one appearance 
on the backplane connector system. For the Tone/Clock angel firmware the TN2182 must 
be removed from the system, the TN795 must be in an even slot and the TN744 must be 
in the system.

does not support ICLID on the analog trunk to the CO, nor Caller ID on the line side to the 
telephone.
TN798B  Processor for csi only
The TN798B processor platform runs at 25 MHz and integrates many functions of the 
TN790 processor and the TN777B NETCON circuit packs onto a single circuit pack. 
These functions include a 32-bit RISC CPU complex and a maintenance processor 
complex providing serial communications and maintenance functions. In addition, the 
TN798B terminates ISDN LAPD signaling over the DEFINITY TDM bus from PRI and BRI 
trunk circuit packs. 
The RISC CPU complex provides 4 to 32 MBytes of Flash PROM. The DRAM is provided 
via 1 SIMM. The TN798B contains 16 MBytes of DRAM. The flash is not interleaved. 
The TN798B processor does not provide X.25 communications nor does it provide a 
duplication option. The TN798B does not contain an on-board modem. Instead, an 
external modem must be connected to the RS-232E port previously used for the internal

circuit pack in R8r or later systems. The TN1654 converter complex installs in place of the 
conventional fiber and supports from 1 to 4 T1 or E1 facilities, providing a total of 92 T1 
channels (or 120 E1 channels) in each direction between the PPN and the EPN. This 
capacity is enough for an EPN to easily support several hundred stations.
R8r or later architecture provides for EPNs that are remotely located from the PPN. EPNs 
within 5 miles (8 km) of the PPN may be coupled using multimode fiber optic cable or 
within 22 miles (35.4 km) using single-mode fiber optic cable. When the distance between 
the PPN and the EPN exceeds 5 miles (8 km) (multimode), or 22 miles (35.4 km), 
single-mode, or private right-of-way is not available, connect using a DS1 converter 
complex. A DS1 converter complex consists of a pair, 1 at each end, of DS1 converter 
circuit packs and the associated T1/E1 facilities.
A new set of Y-cables is required by the TN1654 to connect to a TN570B Expansion 
Interface circuit pack for system communication. 
TN1655  Packet Interface for r only
