Connection Data for SM_V35_V11 Interfaces
The SM_V35_V11 supports two channels of V.35 or V.11 interface. Each interface can independently be
configured as V.35 or V.11/X.24 and can be mapped to unframed E1 or N x 64K of framed E1 (the interface
rate N is configurable). The following table lists the pin assignment of V.11 interfaces for a typical connector
and the color of the wire connected to the corresponding pin in the cables offered by ECI for connecting the
tributary connector and a distribution frame.
