Features
The PM8318 TEMAP 168 is a high density T1/E1 framer with integrated
VT/TU mappers and M13 multiplexers. This feature-rich device is
ideally suited for applications performing high-density transport or
termination of channelized DS3 or unchannelized DS3, E3, T1, or E1
over existing SONET/SDH facilities.
- Processes 168 T1s/126 E1s or half of an STS-12/STM-4.
- Integrates SONET/SDH and DS3/E3 functionality as well as 168
T1/126 E1 bidirectional PMON-capable transceivers.
- SONET/SDH functions include high order path processing, low
order path processing, T1/E1 to VT/TU mapping, and DS3/E3 to
AU-3/TU-3 mapping.
- DS3/E3 functions include six DS3/E3 bidirectional PMON-capable
transceivers and six M13 multiplexers.
- Line side interfaces include:
- A 77.76 MHz byte wide parallel TelecomBus supporting an
STS-12/STM-4.
- Two Working and two Protect 622 MHz serial TelecomBus
interfaces supporting a full STS-12/STM-4 of traffic.
- Six serial DS3/E3/EC-1 links.
- System side interface is a 19.44 MHz or 77.76 MHz byte serial SBI TR
bus used to connect T1/E1 line interface units.
- Provides an input and output STS-1 level cross-connect to:
- Groom incoming and outgoing data streams; or
- Connect two TEMAP 168 devices in parallel to process a full
STS-12/STM-4 of bandwidth.
- Provides a serial interface for extracting and inserting the low order
path and the high order path.
- Supports bit asynchronous mapping of T1/E1 tributaries into
SONET/SDH.
- Generates and terminates Low Order Path overhead (V5, J2, Z6, Z7
bytes).
- Provides Full Duplex performance monitoring for T1, E1, DS3, and E3
tributaries provided for add and drop directions.
- Supports inband error reporting by updating the REI, RDI, and
auxiliary RDI bits in the V5 byte (G1 byte for TU-3) with the status of
the received tributary.
- Supports M13 and C-bit parity DS3 formats.
- Provides High Order Path overhead (J1, B3, C2, G1 bytes) processing
and the corresponding errors and indications.
|
- Each T1 transceiver can be independently configured to support the
common DS1 signal formats (with full SF/ESF support or partial
SLC®96 support) or bypassed (unframed mode).
- Provides in-line DS3/E3 and T1/E1 framers and transmitters for each
data path allowing true bi-directional performance monitoring of
each path.
- Each T1 transceiver:
- Detects the presence of Yellow and AIS patterns.
- Integrates Yellow, Red, and AIS alarms.
- Supports ingress performance monitoring, ESF bit-oriented
codes, HDLC messages on the ESF data link, inband loopback
codes, and PRBS generation/detection.
- Each E1 transceiver:
- Detects the presence of remote alarm and AIS patterns.
- Integrates Red and AIS alarms.
- Supports ingress performance monitoring, support for HDLC
messages in the National Use bits, Sa-bit codewords, and V5.2
link ID detection.
- Contains desynchronizers and jitter attenuators (JATs) that provide
Jitter and Wander compliant E1, T1, DS3, and E3 physical interfaces
without the need for external jitter attenuators.
- Provides an input and output T1/E1 tributary cross-connect to allow
switching of tributaries between the VT/TU mapper, M13 multiplexer
and SBI TR bus.
