26、 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 Mbitts PDH interfaces. The present document is applicable to systems carrying an STM-4 signal over a pair of RF channels each with a c
27、apacity of 2 x Synchronous Transport Module-level 1, (2 x STM-I), 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. The parameters specif
28、ied fall into two categories: a) those required to provide compatibility between channels from different sources of equipment on the same route, connected either to separate antennas, or to separate polarizations of the same antenna. This category also includes parameters providing compatibility wit
29、h the existing radio-relay network: b) parameters defining the transmission quality of the proposed systems. Compatibility requirements with analogue and digital systems on the same hop and at nodes are examined. However, they cannot be defined with exactness due to the fact that analogue systems an
30、d some digital systems are not standardized. Compatibility requirements are, therefore, limited to allowing the operation of digital and analogue channels on separate ports of the same antenna (see annex B). The standardization includes the following specifications: a) transmitter and receiver chara
31、cteristics; b) baseband and Radio Frequency (RF) interface characteristics; c) diversity system characteristics; d) STM-4, or STM-1 baseband transport interface; e) PDH baseband transport interfaces mapped onto an SDH frame. Baseband interfaces have to be considered for STM-4 signals and STM-1 signa
32、ls are in accordance with ITU-T Recommendations 6.957 37 and G.707 33 respectively. Safety aspects are outside the mandate of ETSI and they will not be considered in the present document. 2 References The following documents contain provisions which, through reference in this text, constitute provis
