Codex 3500 DSU/CSU, Technical Data
   For HP Remote Bridge and Multiplexer
   Product Number CODX-3500
Codex 3500 combines the functionality of multiple digi-tal transmission
devices into a single, high compact unit. It supports digital
transmission requirements in a broad range of operating environments,
from 2.4 Kbps to 56 Kbps. It can be con-nected with HP2335A
multi-plexer, HP remote bridge, or HP router to transmit data via DDS
facili-ties from central sites to re-mote sites. The Technical
In-formation Guide (TIG) will show how this DSU/CSU can be configured
and connected to work with HP systems.
o Versatile, cost-efficient DSU/CSU that can meet a wide range of
  digital transmission speeds and applications
o Combines all data rates in a single unit; supports 2.4, 4.8, 9.6,
  19.2, and 56 Kbps
o Unique rate adaption function permits use of lower priced digital
  services
o Enables diagnostic testing of local and remote units in both
  point-to-point and multipoint configurations
o Integral timing buffer reduces data errors caused by timing variations
  between different digital services
o Supports asynchronous to synchronous conversion up to 19.2 Kbps
o Fully tested and qualified to be compatible with HP networking systems

Functional Description
The Codex 3500 was tested and qualified to be compatible with
HP computers and networking systems. Among the tested configurations
include the link from central host computer to remote site via the
combination of HP remote bridge and DSU/CSU over DDS, the link from
central site to remote site via the combination of HP router and DSU/CSU
over DDS, and from central site to remote site via HP 2335A multiplexer
and DSU/CSU over DDS. Refer to the Technical Information Guide (TIG) for
more technical information on how to configure the modem with HP systems
and other considerations.
   Note: To connect the DSU/CSU to HP remote bridge, a DB25(M) to
V.35(M) DTE cable is needed (order number: CODX-77999). To connect the
DSU/CSU to HP router, a DB25(M) to V.35(F) DTE cable is needed (order
number: CODX-48523).
