PRI ISDN
North American PRI-ISDN uses DS1 (T1) as the Layer-1 transport while the rest of the
world (except Japan-J1) uses E1 as the transport Layer-1. North American PRI-ISDN
format is 23B+D, the B channels are bearer data\voice channels and the D is the sig-
naling channel that uses Q.931 codes. 23B+D occupy 24 DS0 channels of a DS1.
The test set PRI ISDN interface uses the DS1-B bantam jacks on the front panel. The
RX is the input and TX is the output of the DataScout 10G test system. Power on and
configure the test set first before connecting the PRI circuit under test.
To test a PRI circuit connect bantam leads to the T1/E1
“B” port bantam and a butt-set
or analog phone to the 2-wire signaling RJ-11 port.
Test Interface Connections
To connect the test interface to the device under test you must select the proper patch
cable depending on which interface you are testing and the termination type if using
the optical ports. There is no specific order of connection required. You can connect
the patch cord to the test device or network device first.
