The analog modem at the same end as the MultiDSU64K must have
External Timing enabled; the modem at the end of the off-net
extension must have DDS Timing enabled.
In MultiDSU64K applications that use controlled carrier, the CTS
delay for the analog modem at the end of the off-net extension must
be longer than the CTS delay of the MultiDSU64K.
