SDH FrameSDH FrameFrame Header + Payload = Synchronous Transport Module (STM)
SOH - Section OverheadSynchronisation, supervision and maintenance
PayloadPath signals (PDH, IP, ATM)
SDH Frame StructureSDH Frame Structure
◆ Use of SOH is implemented according to ITU-T G.707◆ Each byte in SOH is 64kb/s channel◆ Some SOH byte used for framing, performance monitoring &
internal signalling◆ Others unused bytes used for 64kb/s user channels, 2Mb/s
wayside, SVCE telephone or DCC
SDH Multiplexing StructureSDH Multiplexing Structure
SOH - Section OverheadSOH - Section Overhead
◆ A1: Frameword (11110110)◆ A2: Frameword (00101000)◆ J0: Regenerator Section Trace◆ B1: BIP-8 checksum for RST◆ B2: BIP-24 checksum for MST
3 bytes in RSOH (MS#1, MS#2 and MS#3) are used for radio specific purposes:◆ MS#1: Radio Protection Switching control◆ MS#2: Radio Protection Switching control◆ MS#3: RF-id, remote reset, ATPC and E/M-wire for E1, E2 and F1
SOH - Section OverheadSOH - Section Overhead
◆ E1-byte: Orderwire◆ F1-byte: User channel, V.11 or G.703 interface optional◆ D1-D3 bytes: Embedded control channel - Regenerator (ECC-R)◆ D4-D12 bytes:Embedded control channel - Multiplexer (ECC-M)◆ E2-byte: Orderwire available when MS-termination is used◆ K1/K2: APS signalling (not used in the radio relay equipment)◆ MS-RDI: Multiplex Section - Remote Defect Indication◆ S1 (b5-b8): Synchronisation Status Message◆ M1-byte: Multiplex Section - Remote Error Identifier (MS-REI) ◆ B1/B2-byte: BIP-8 / BIP-24◆ A1/A2-byte: Frameword◆ H1-H3 bytes: Pointer

The Radio Relay is normally configured for RST, avoiding theneed for synchronisation as all bearers and directions areindependent and transparent for the multiplexerssynchronisation.

◆ With this configuration, equipment will monitor andre-generate B1 pulses. M1 REI & B2 pulses will onlybe monitored.
◆ Synchronisation:✹ Normal Situation
➤ Radio transmitting direction : STM-1 signal derived fromline side
➤ Radio receiving direction : STM-1 signal derived fromradio side
✹ Failure➤ Both directions : Internal 2.048MHz oscillator (AIS insert

◆ Maximum number of frequency on each polarisation is four◆ Maximum system configuration is 7+1 / 8+0 on one terminal◆ Maximum of sixteen STM-1 can be carried in the frequency band with eight
RF channels (or more).◆ Requires optional XPIC feature on all radio channels

◆ Space Diversity System is using 2 antenna (denoted “Main” & “Space”) mounted apart
◆ Connected to one Space Diversity Transceiver to achieve better performance◆ Requires different waveguide length for 2 different antenna◆ Results in different signal propagation delays at the main and Space receiver
inputs
◆ To compensate this effect, transceiver can add delay in one of the signal paths◆ Optimal receiver performance requires an accurate delay compensation.◆ The two antenna signal are combined to get a single received signal for the
demodulation process◆ Combiner operates in either automatic mode or manual mode.
➤ Automatic Mode : Controlled by signal quality criteria derived internally in the transceiver
➤ Manual Mode : User selects which signal to use
◆ Delay Calculation = “Main / Space Waveguide Length Diffetence” x 4.2ns
◆ Valid Input Range : -6ns to +130ns
