TL3M
TXC-03453B
PRELIMINARY TXC-03453B-MB, Ed. 3
FEATURES
The TL3M supports the following features. Please note that the convention used here is that the transmit (or
add) direction is from the DS3/E3 line signal (rail or NRZ) to the SDH/SONET format (Telecom Bus), while the
receive (or drop) direction is from the SDH/SONET format to the DS3/E3 line.
Bus Timing (Telecom Bus):
The TL3M provides the following bus timing modes for the Telecom Bus modes of operation:
• Drop bus timing
• Add bus timing
Mappings:
The TL3M provides the following mapping features:
SDH/SONET Rates:
The TL3M provides the following Telecom Bus rates and format mappings:
Other Telecom Bus Features:
The TL3M provides the following additional bus features:
• SDH/SONET interface Drop bus
• Add bus timing is derived from the Drop bus timing input signals
• Add bus timing is supplied and is independent of the Drop bus timing
• Maximum of three channels for either E3 or DS3 line signals
• STM-1 AU-4 VC-4 format
• STS-3 format
• Same drop and Add bus for all channels
• Add bus contention indication (same channel assignment)
• Broadcast mode
• STS-3 STS-1s (19.44 Mbyte/s)
• STM-1 VC-4 (19.44 Mbyte/s)
• Input parity check with alarm monitoring
• Input loss of clock detection
• Loss of J1 reference
• Drop bus: C1J1, SPE, optional C1, data, clock, and parity signals leads are inputs
• Add bus: data, parity, and add indication signal leads are outputs
• Drop bus: C1J1, SPE, optional C1, data, clock and parity signal leads are inputs
• Add bus: clock, C1J1, and SPE signal leads are inputs; data, parity, and add indication signal
• Each E3 or DS3 signal into TUG-3 format
• Each DS3 signal into STS-1 format
• Add Bus: high impedance Add bus if there is contention
• Drop Bus: multiple channel assignment to the same TUG-3
• Odd parity
• Bus signals
• Stuck high or low
leads are outputs
