but you must make sure same time slot configuration and same setting of
PCM30/31 and CRC. However, bandwidth auto-follow function and E1
loop-back test of remote converter cannot be used.

7. Compatibility of Raisecom products with V.35 interface

Answer

：

RC800-30B-FV35 series can also interoperate with other Raisecom

products that have similar functions, such as:

RC903-V35FE1 standalone V.35 to fractional E1 interface converter

RC904-V35FE1 module V.35 to fractional E1 interface converter

SUBM-FV35 N×64K V.35 interface extension module that can be installed

in extendable optical multiplexer.
