2 The SONET/SDH Ultramapper
(continued)
B3 is monitored either in bit or block mode. Provisionable N-times detection counters are implemented for C2, F2,
F3, N1, and K3 bytes. The K3 APS byte and N1 TCM byte can be monitored as an entire 8-bit word or two 4-bit nib-
bles.
The receive path overhead access channel (RPOAC) provides access to all the path overhead bytes. Even or odd
parity is calculated over all bytes. It has a data rate of 8 bytes per 8 kHz frame and consists of clock, data, and an
8 kHz synchronizing pulse.
In the transmit direction, J1 path trace insertion, B3 calculation and insertion, C2 signal label insertion, REI-P and
RDI-P insertion; F2 insertion, H4 multiframe insertion, F3 path user byte insertion, K3 insertion, N1 byte insertion,
and AIS-P insertion via POAC or software control is supported.
The transmit path overhead access channel (TPOAC) allows the insertion of all overhead bytes besides B3 which
is automatically calculated. Even or odd parity is checked over all bytes. Bytes which are not enabled for insertion
are set to an all-ones or all-zeros stuff value. The Ultramapper sources a clock and an 8 kHz synchronizing pulse
and receives the data at a rate of 8 bytes per 8 kHz frame.
2.5 STS-3/STM-1 Overhead Termination and Pointer Processing
The information on overhead termination and pointer processing is not available at this time.
2.6 STS-3/STM-1 MUX-DeMUX
The STS-3/STM-1 (AU-4) multiplexer provides three modes of operation: STS-3, AU-4, and STS-1.
In STS-3 mode, the block multiplexes and demultiplexes up to three STS-1 signals to/from a SONET STS-3 signal.
In AU-4 mode, it provides the functionality to MUX/deMUX up to three AU-3 signals to/from a STM-1 (AU-4) signal.
In STS-1 mode, it provides the functions to generate and terminate a single STS-1 signal.
The STS-3/STM-1 MUX function takes the bytes in the order they are present on the telecom bus and multiplexes
them into the high-speed signal. Grooming of the VTs/VCs is performed in the SPE mapper of each of the three
devices.
2.7 STS-3 Serial Interconnect
The information on the STS-3 serial interconnect is not available at this time.
2.8 STS-12/STM-4 Pointer Processor
The information on the STS-12/STM-4 pointer processor is not available at this time.
2.9 STS-3/STM-1 Interface to Mate Devices
The Ultramapper can communicate with up to three mate devices via STS-3/STM-1 interfaces. One Ultramapper is
provisioned as a master and the other three are provisioned as slaves. This provides for full external termination of
the STS-12/STM-4 payload.
