PE1_63 Card Connection Data
The PE1_63 provides 63 balanced E1 tributary interfaces and has three twin 68-pin VHDCI female
connectors. Each twin 68-pin VHDCI connector serves 21 × E1 receive and transmit signals. The tributaries
supported by each connector are marked alongside the connector:
1-21
,
22-42
, and
43-63
.
The following figure identifies the connector pins, as seen when looking into the connector. The following
tables list the pin assignment for a typical connector. They also list the color of the wire connected to the
corresponding pin in the cables offered by ECI for connecting between the tributary connector and a
distribution frame.
The tributary numbers appearing in the table are given for the
1-21
connector. To obtain the correct
tributary numbers for other connectors, interpret the numbers as representing the number of the tributary
in its group (for example, in connector
22-42
, 7 represents E1 tributary 28).
