Verifying R2 / Isdn Pri Connection Status - Davolink DV-332 User Manual

6.4.2. Verifying R2 / ISDN PRI connection status

1) R2 connection status
PBX transmits signals by unique tones because of R2 MFC signaling type. Therefore, GW cannot show
its connection status. You have to make a call to test whether it works well or not. And you need to
inspect debugging message when you cannot send a call.
2) ISDN PRI connection status
ISDN PRI uses one of E1 31 channels as a signal transmit channel to send and receive messages so
that it can verify its connection status. In order to use ISDN PRI channel, this signal transmit channel
should be connected. This means that LAPD channel is established. If LAPD channel is established as
follows, channel status will be "connected". Note that following example represents that two
digital trunks are configured and working properly: one digital port for ISDN PRI, and the other for
R2 MFC.
