14 1-Port and 2-Port ISDN-PRI Network Module Configuration Note

PRI Module LEDs

Table 4 lists pinouts for the CE1/PRI cables.

PRI Module LEDs

All network modules have an enable LED. This LED indicates that the module has passed its
self-tests and is available to the router.

All PRI modules display four additional LEDs for each port. These LEDs are described in Table 5.

Table 5

ISDN-PRI Network Module LEDs

The following sections illustrate these LEDs.

1. Tx = transmit. Rx = receive.
