DIM 2435

The Data Interface Module (DIM) 2435 provides:

•

One (1) V.35 connector (34-pin Winchester type) for

connecting either DTE or DCE to the DIU 2130

•

One (1) RS-449/422 connector (DB-37) for connecting either

DTE or DCE

Figure 1-5 DIM 2435, V.35/RS-449

DIM 2530

The Data Interface Module (DIM) 2530 provides:

•

Dual (2) EIA 530 connectors (DB-25) for connecting either DTE

or DCE

Figure 1-6 DIM 2530, EIA 530

NOTE:

When connecting DCE to a DIU 2130, a cross-over cable must

be used.

CSU Interfaces

T1 Mux

(CSU/DSU) Mode

In a typical single-DIU configuration (Fig 1-4, A), each data port

operates at 672 kbit/s and therefore requires 12 channel time slots

on the T1 network (672 kbit/s = 12 channels

56 kbit/s each) for

the proper transmission bandwidth. The sum total of the

bandwidths of the two data equipment ports cannot exceed 24

channels (1.344 Mbit/s) in this example.
