DIU 2130 Overview
Verilink 1-3
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.
