scope:
The present document specifies parameters for digital radio-relay systems with Transport Module-level 4, (1 x STM-4), interface, and in addition, optional 140 Mbit/s PDH interfaces. The present document is applicable to systems carrying an STM-4 signal over a pair of RF channels each with a capacity of 2 x Synchronous Transport Module-level 1, (2 x STM-1), designed to operate in defined bands utilizing 40 MHz between adjacent crosspolar channels. Optionally, a single RF channel can be used to transport 2 x Synchronous Transport Module-level 1, (2 x STM-1), signals.
