CAUTION!
When a D channel that is either in actv (active) or conf (configure) state is returned to standby
state, Interface ID and BMap settings are lost and returned to their default values. Thus,
caution should be exercised before returning a D channel to standby state.
WAN
The WAN setting shows the WAN link carrying this D channel. In standard applications (23B
+ D), the WAN link will be the same as the WAN link carrying the B channels. In NFAS
applications, this may not be the case.
TS
The TS (timeslot) setting identifies the timeslot on the WAN link that carries this D channel.
Even though the system allows values that range from 1-24 for T1 links and 1-31 for E1 links,
in almost all cases, TS 24 will be used for T1 applications and TS 16 will be used for E1
applications (when available).
RATE
The Rate parameter allows users to choose the rate of the D channel. Even though the
equipment allows values of 56k and 64k, in almost all cases, the rate of 64k will be used.
SIDE
The options for this parameter are user (user side) and net (network side). See discussion
earlier in this chapter that describes which side to choose.
SW. TYPE
The Switch Type is selected from the possible central office equipment types to which the
system is connected. The choices are fjtsu (Fujitsu), att_4 (AT&T #4ESS), att_5 (AT&T
#5ESS

), dms_1 (DMS-100

), dms_2 (DMS-200
®
) ni_2 (National ISDN II), dpnss (Digital
Private Network Signaling System), dass2 (Digital Access Signaling System #2), net_5
(European ISDN), and mcl.
DATA INV
The Data Inversion option allows users to select whether or not the HDLC (High level Data
Link Control) will invert the data bits when B8ZS format is not available. In almost all cases,
DATA INV should be set to no.
