Data Communications Support
The 7500B Data Module is connected by a D8W cord to the MLX port on the
008 MLX or 408 GS/LS-MLX module (Release 2.0 only).
The PRI interface is established from the 100 DS1 Module to the CSU and then
to the ESS switch and the PRI interface.
For the purposes of the compatibility tests, a Shore Microsystems Model SM-
100 RS-232/V.35, converter was used to test this configuration. The converter is
customer-supplied equipment that can be purchased from a data equipment
vendor.
Fax Configuration 3: Direct V.35 Interface
If the Group IV (G4) Fax machine is equipped with a CCITT-V.35 interface, use
this configuration method. If the fax machine is equipped with a V.35 interface,
an optional connection board must be used with the 7500B Data Module. This
configuration is required if the customer does not wish to purchase a converter
or if the dialing is to be done on the front face of the 7500B Data Module. This
connection requires dialing from the 7500B Data Module, that is, the 7500B
Data Module must be located in a work area where it cannot be accidentally
reconfigured. Accidental reconfiguration could cause the fax transmissions to
malfunction, Also, dialing for fax transmissions from the 7500B Data Module is
subject to a high error rate due to misdials.
Figure 5-4 shows the connection between a Group IV (G4) fax machine and a
7500B Data module using an EIA-V.35 interface.
