RCS20 M:N Redundancy Switch Revision 15
Remote Operations MN-RCS20 and CD-RCS20
A–27
A.3.7 Opcode <2200h> Relay Command or Query to Modem
Command Data Field (n+1 bytes):
<1> Channel Number Channel number for the modem for which the message is to be
relayed (0 to 9 for the RCS20)
RLLP Packet from
Modem Complete, addressed RLLP message block with (variable number of
bytes) sync byte, source address, destination address, Opcode, byte
count, data field and checksum) (Contents of Response Packet Data
Field: Dependent upon message relayed to modem.
A.3.8 Opcode <2202h> Set RCS20 Configuration
Command Data Field:
<2> Nonvolatile Bytes Number of nonvolatile RCS20 configuration memory bytes, including
these 2 bytes (221 decimal for RCS20)
<1> Number of Channels Maximum number of prime and backup channels available to the
RCS20 switch. (10 decimal for RCS20 as of Release 1.0)
<1> Nonvolatile Bytes per
Channel Number of nonvolatile memory bytes per channel. This number may
vary with the release number. (10 bytes for RCS20 as of release 1.0
and 13 bytes as of release 4.0)
**Remote M&C developers must make use of this value to find out how
many bytes per channel are being transmitted.
