TXC-03305, M13X VLSI Device (DS3/DS1 Mux/Demux). This single-chip device pro-
vides the functions needed to multiplex and demultiplex 28 independent DS1 signals
to and from a DS3 signal with either an M13 or C-bit frame format. It includes some
enhanced features relative to the M13E device.
TXC-04228, T1Mx28 VLSI Device (DS1 Mapper 28-Channel). Maps twenty-eight
1.544 Mbit/s DS1 signals into any twenty-eight selected asynchronous or byte-syn-
chronous mode VT1.5 or TU-11 virtual tributaries carried in a SONET or SDH syn-
chronous payload envelope.
TXC-04251, QT1M VLSI Device (Quad DS1 to VT1.5 or TU-11 Async Mapper-
Desync). Interconnects four DS1 signals with any four asynchronous mode VT1.5 or
TU-11 tributaries carried in SONET STS-1 or SDH AU-3 rate payload interface.
TXC-05150, CDB VLSI Device (Cell Delineation Block). Provides cell delineation for
ATM cells carried in a physical line at rates of 1.544 to 155 Mbit/s.
TXC-05427C, COBRA Device (COnstant Bit Rate ATM Adaptation Layer 1). This is a
four-channel device that implements all of the functions needed for circuit emulation
over ATM. Both Unstructured service (e.g., 1544 kbit/s and 2048 kbit/s) and Struc-
tured service (e.g., n x 64 kbit/s) are supported. COBRA offers three clock modes:
internal clock recovery based on the Synchronous Residual Time Stamp (SRTS),
clock recovery based on the FIFO fill level (adaptive FIFO), and an external clock
mode.
TXC-06101, PHAST-1 VLSI Device (SONET STS-1 Overhead Terminator). This
device provides features similar to those of the TXC-03011 SOT-1E device, but it
operates from a power supply of 3.3 volts rather than 5 volts.
TXC-06103, PHAST-3N VLSI Device (SONET/SDH STM-1, STS-3 or STS-3c Over-
head Terminator) This PHAST-3N VLSI device provides a COMBUS interface for
downstream devices and operates from a power supply of 3.3 volts.
TXC-06125, XBERT VLSI Device (Bit Error Rate Generator/Receiver). Programmable
multi-rate test pattern generator and receiver in a single chip with serial, nibble, or byte
interface capability.
