3.20.2 HDLC TRANSMITTER
form HDLC packet data stream.
3.20.2.1 HDLC Channel Configuration
#2 & #3) per link are provided for HDLC insertion to the data stream to
be transmitted. In T1/J1 mode SF & SLC-96 formats, two HDLC Trans-
mitters (#2 & #3) per link are provided for HDLC insertion. In E1 mode,
three HDLC Transmitters (#1, #2 & #3) per link are provided for HDLC
insertion. Except in T1/J1 mode ESF & T1 DM formats, the HDLC
channel of HDLC Transmitter #1 is fixed in the DL bit (in ESF format)
and D bit in CH24 (in T1 DM format) respectively (refer to Table 13 &
Table 14), the other HDLC channel is configured as the follows:
the corresponding TDLEN bit is set to ‘1’.
