	(external)
Layer 1	Transparent	80 Bits	HDLC
		Framing
Layer 2	None	None	LAPB/LAPD
Layer 3	None	None	ISO8208 T.70
			NL/ V.120
Error Control	No	No	Yes
V.42bis	No	No	Yes
Async or Sync	Sync	Async	Async
Bundle	Yes (Note)	No	Yes
Max. Line	64Kbps	38.4 Kbps	64Kbps

AT-Command	ATB11&M1	ATB10	ATB0:
Configuration	(Sync Data)		Transparent
	ATB11&M3*I1		ATB01: T.70
	(V.25bis Sync HDLC)		NL/ ATB20

Note : BONDING protocol for synchronous mode will be F/W upgradeable at ZyXEL‘s option.

Answering a V.110 call

Once you set the proper V.110 communication mode, there is no need to configure the ISDN mode to the protocol of an incoming call. The omni will be able to determine the correct protocol to use by examining the data coming in from the remote site if the device is set to auto-answer or once an answer command is issued.

To allow the TA to answer the incoming call, you need to set S0 to a value greater than 0 (i.e. ATS0=1). If S0 is not set (S0=0), the DCE
