Chapter 2 - Technical Information

V.35/RS-449/RS-530 Network Interface Module

The following paragraphs provide technical information about the

V.35/RS-449/RS-530 network interface module available with the

ViewStation EX, ViewStation FX, and VS4000.

The system’s V.35/RS-449/RS-530 network interface module is not

interchangeable with the previous V.35 network interface module.

The new module uses HD-44F connectors for ports 1 and 2, and uses

a keyed RJ-45 connector for the serial link to the back panel of the

ViewStation FX or VS4000. The cable used with the

V.35/RS-449/RS-530 network interface module is the same as is

used for the PRI network interface module. It is shown in Figure 2-5.

An HD-44M to DB-25F adapter cable is available to connect existing

ViewStation DB-25 interface module V.35 network cables.

“Common speeds” are divisible by both 56 and 64. The

V.35/RS-449/RS-530 network interface module supports the

following common speeds:

❑ 448 Kbps

❑ 896 Kbps

❑ 1344 Kbps (E1 only)
