Composite Interface Selection
Interface cards are used to determine the interface type (X.21/V.11, V.24, V.35 etc.) of the
composite link. It is necessary to use the corresponding external
cable
to make connection
once the interface card has been fitted.
It is necessary to set link positions on the composite interface cards as follows:
Interface
Link Number
DTE Setting
(Network)
V.11 (IA75035)
N/A
N/A
V.24 (IA75038)
LK1, LK2
CMP
V.35 (IA75039)
LK1, Nearest J1
EXT
LK2, Nearest J2
EXT
The interface cards may be accessed when the cover is removed, as described in the
Mechanical Construction section on page 25, the position for each being shown in the above
diagram. Anti-static precautions must be taken whilst fitting or changing the interface cards
which simply plug into the motherboard at the positions shown.
Composite Network Connection
The Sprint 2 Multiplexer supports many different Network Interfaces including X.21/V.11,
V.35, G.703 and V.24, others being available now or in the near future (please contact Black
Box for further details).
The composite port appears on the back panel as a 15 way D-type connector, the pin-out for
each interface standard being shown in Appendix F. Correct cables for Network connection
are shown in Appendix I.
Composite Link Parameters
Parameters may be toggled using the

settings must be activated using
