face.
s Synchronous (16 MHz to 66 MHz)/asynchronous
microprocessor interface modes.
s Microprocessor data bus parity monitoring.
s Summary of 2 level priority interrupts from major
functional blocks/maskable.
s Separate device interrupt outputs for automatic pro-
tection switch and the Ultramapper global interrupt.
s Global configuration of network performance moni-
toring counters operation.
s Global software resets.
s Global enabling and powering down of major func-
tional blocks.
s Miscellaneous global configuration and control.
SPEMPR Features
s The SPE mapper accepts/delivers TUG-2 data from/
to the VT mapper. The TUG-2 data is mapped/
demapped either to/from an AU-3/STS-1 signal for
the North American digital systems or to/from a
TUG-3 signal for the ITU-based systems.
s The SPE mapper accepts/delivers DS3 data from/to
the M13 MUX/deMUX. The DS3 data is mapped/
demapped either to/from an AU-3/STS-1 signal for
the North American digital systems or to/from a
TUG-3 signal for the ITU-based systems.
s The SPE mapper accepts/delivers a clear DS3 signal
at 44.736 Mbits/s rate. The clear DS3 signal is
mapped/demapped essentially the same way as
M13 signal described above.
s The SPE mapper accepts/delivers E3 data from/to
the E13 MUX/deMUX. The E3 data is mapped/
demapped either to/from an AU-3/STS-1 signal for
the North American digital systems or to/from a
TUG-3 signal for the ITU-based systems.
s The SPE mapper accepts/delivers a clear E3 signal
at 34.368 Mbits/s rate. The clear E3 signal is
mapped/demapped essentially the same way as E13
signal described above.
s The SPE mapper has a DS3/E3 loopback circuit
placed for the functions of demapping and remap-
ping a DS3/E3 signal. It is particularly useful in cases
where a DS3/E3 signal mapped as an AU-3/STS-1
signal has to be remapped as a TUG-3 signal or vice
versa.
s The SPE mapper supports a path overhead access
channel more commonly known as the POAC chan-
nel. Seven path overhead bytes namely J1, C2, F2,
H4, F3, K3, and N1 may be inserted/dropped
through this channel. This channel works as the
master, which means that this channel provides a
clock in both transmit and receive directions and
POH data may be inserted by the user on the trans-
mit side or dropped by the block in the receive side.
s Path overhead byte B3 (BIP error) generation/detec-
tion and programmable BIP-8 bit error rate insertion.
s Programmable clear on read/clear on write registers.
s Signal fail and signal degrade indicators available to
report bit error rates above a certain programmable
threshold.
