HDLC OPERATION
The modem is capable of performing HDLC framing ( High Level Data Link control ). The modem uses the
SDLC ( Synchronous Data Link control ) in an eight bit octet format which is a subset of HDLC.
1 HDLC Frames
Information on an HDLC link is transmitted by means of frames. The information is organized into a format
specified by an international standard that enables the synchronization between the transmitter and the
receiver. An HDLC frame has the following parts :
Flags
Address Field
Control Field
Information Field
Fame Check Sequence
The frame check sequence computation uses the cyclic redundancy check ( CRC ) method and implement a
polynomial specified in ITU-T T.30 and X.25 as follows :
X
16
+ X

The HDLC is functional under the following transmitter and receiver modes:
V.17 ( KS16114 )
V.29
V.27ter
V.21 Ch. 2
V.21 Ch. 2 with DTMF Receiver
