C&M Channel defines the kind of channel that will be used by the
startup sequence for negotiation. Only
Disabled
is available when
Vendor is set to Ericsson .

Auto
(default): Overhead byte #Z.66.0 can use any of the HDLC
rates and Overhead byte #Z.194.0 can use any of the Ethernet
Subchannel in the negotiation process.

HDLC : Only overhead byte #Z.66.0 is used with the configured
HDLC Rate during the negotiation process. Ethernet #Z.194.0 byte
is set to rr00 0000 as it is disabled.

Ethernet
: Only overhead byte #Z.194.0 is used with the configured
Ethernet Subchannel during the negotiation process. HDLC
#Z.66.0 byte is set to rrrr r000 as it is disabled.

Disabled : Both HDLC Rates and Ethernet Subchannel are disabled
to simulate a Passive Link. Ethernet #Z.194.0 byte is set to rr00 0000
and HDLC #Z.66.0 byte is set to rrrr r000. Only available with
Base
Station
emulation mode.
C&M table indicates either the received (HDLC or Ethernet) or
negotiated (Auto) C&M for Ethernet subchannel and HDLC rates in
Mbit/s. A red background indicates either a C&M type mismatch or
HDLC Rate/Ethernet subchannel mismatch compared to the generated
C&M channel. An arrow is displayed indicating which C&M Channel
should normally be selected as per the standard rules.

Subchannel selects the Ethernet Subchannel number: 20 to 63 where
63 is the lowest bit rate and 20 the highest.
