VC-4
The VC-4 consists of a 9-row by 261-column payload structure withthe first column allocated to VC-4 path overhead (POH).
The STM-1 format consists of an AU-4 and section overhead (SOH).The AU-4 has a fixed phase relationship with respect to the STM-1 frame.The AU-4 pointer is located in the fourt row of the first nine colums of theSTM-1 frame between the bytes of the SOH. The remaining 261 colums of the STM-1 are allocated to the AU-4.
The phase of the VC-4 is not fixed with respect to the AU-4.Threfore the location of the first byte of the VC-4 with respect to theAU-4 frame is given by the SU-4 pointer.

N L 2 9 x S T M -1 Radio re lay equipment
Design philosophy for the STM-1 radio
u Introducing new STM-1 modem together with existing RF equipment (Equal or less BW than the 140 Mb/s PDH radio).
u 128 TCM modulation needed to limit the bandwidth.
u Both 140 Mb/s PDH and STM -1 data interface, electrical and optical.
u Can be used as MST and RST.
u Automatic N+1 protection switching for both STM -1 and 140 Mb/s interface.
u Integrated supervision system with on-line monitoring of transmission quality and system status.
u Interface to TMN with Q - protocol.
u Compact slim-rack design which easily can be expanded with more channels.

Hot Stand by configurationHot Stand by configurationHot Stand by configurationHot Stand by configuration
Hot Standby configuration provides 1+1protection against equipment failure
No protection against fading
Both automatic and manual switching to standby channel
It is normally used when 1+1 frequency diversity is impossible to use,due to lack of available frequencies
