4. ISDN CAUSE CODES

In addition to the above events, certain recognized ISDN cause codes are sent to the event log from the

ISDN message facility during ISDN EVENTS, L2 MESSAGES, and L2 FORMATTED event categories.

Table 10 lists the codes applicable to the ATLAS 550 and the minimum category required for logging the

cause code event.

Table 8. DP Outgoing Signaling Events
Console Log String Category Event
TX Set Rx ABCD < > Tx ABCD < >1
1 The ATLAS 550 uses only AB signaling bits. The CD signaling bits are a copy of the AB values. These values are
shown in hexadecimal notation. For example, if AB signal bits are 01, then the total signal bits would be 01 01. Putting
that in hexadecimal notation results in an event of Tx set Rx ABCD 0x 05.
INFO ATLAS changed signal bits on port
RX Change Rx ABCD < > Tx ABCD < > INFO E quipment connected to port changed
signal bits
