A.3.2 Opcode <2002h> Query RCS20 Switch Configuration
Query Response Data Field (285 bytes)
Configuration Bytes
<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.
