29503-DSH-002-B
System Side Interfaces–Time Slot Bus (TSB)
Supported Multiplexing
The TSB allows for mapping of all tributary signals to time slots for a transmission to
external devices, such as an HDLC controller. The TSB Interface consists of 2 serial
interfaces: a 51.84 MHz maximum speed payload interface and a 12.96 MHz
maximum speed overhead interface. The payload of tributary signals is mapped to
time slots on the payload bus, allowing for transmission of the following signals’
payload:
Overhead information, including SONET/SDH/PDH overhead and Command and
Status Processor (CSP) information, is transmitted in time slots on the overhead TSB
Interface. The TSB is described
The CX29503 supports the most common multiplexing modes in the SONET, SDH,
and PDH hierarchies. These include the following:
28 × DS1
21 × E1 (G.747 multiplexing)
16 × E1 (E13 multiplexing)
1 × DS3, E3, or STS-1 signal
M13 for DS3-to-DS1 multiplexing
G.747 for DS3-to-E1 multiplexing
E13 for E3-to-E1 multiplexing
SONET STS-1-to-VT1.5 and STS-1-to-VT2.0 multiplexing
SDH TUG-3-to-VC-11 and TUG-3-to-VC-12 multiplexing
