TranSwitch Corporation Offers Complete Family of Framers with the Introduction of a New Octal E1 Framer
SHELTON, Conn.--(BUSINESS WIRE)--March 31, 1999--TranSwitch
Corporation, (NASDAQ:TXCC), announced today the introduction of the
E1FX8, an eight-channel E1 framer designed for voice and data
communications applications.
The E1FX8 joins the T1FX8, an eight-channel DS1/J1 framer, and
TranSwitch's group of quad framers, QT1F-Plus and QE1F-Plus to round
out the Company's framer family. The octal framers, along with the
quad framers are targeted to provide end-to-end solutions for
multipurpose voice and data networking applications such as ATM
multiplexers, frame relay systems, SONET/SDH add-drop multiplexers,
DS1 or E1 monitoring equipment, Internet access equipment with T1/E1
and fractional T1/E1 ports, Computer Telephony Integration products
and digital crossconnect applications.
Like the companion T1FX8, the E1FX8 is an eight-channel E1 framer
that uses a single 3.3V power supply, with 5.0V tolerant I/Os. Its low
power consumption and extensive on-chip support of many functions make
the E1FX8 ideal for high density and highly featured applications.
These octal framers are true off line framers, with all terminal side
options available per channel.
In addition to incorporating all the features of the quad E1
framer, the E1FX8 framer supports both the frame alignment detection
and loss of frame declaration compliant with ITU-T G.706/ETS 300
011(NET5) and the new ETS automatic interworking ITAAB Advisory
No.075. It provides E1 monitor, reference clock and LIU control, on
board AMI or HDB3 codecs and code violation counters, fractional E1 is
supported with an auxiliary input plus gapped clock or marker outputs,
and an intact mode to slip buffer non standard E1 signals. The E1Fx8
has transmit and receive slip buffers and receive de-jitter buffers.
Local, line remote, payload remote and time slot loopbacks (both local
and remote) are provided. ANSI T1.231 fractional T1 compatible
loopback support is provided for single operator fractional T1 or E1
testing through a gateway. An auxiliary port with a time slot
interchanger is provided for applications, such as V5.1 and V5.2 or
ISDN PRI support.
The E1Fx8 supplies the most complete alarm and performance
monitoring. For example, enhanced national bit support is provided for
ISDN, ETS 300 233 & ITU-T I.431, ISRM etc., supporting multiple far
end block error counters, in addition to byte wide read and write
options for each national bit.
The microprocessor interface is compatible with the Motorola or
Intel series of microprocessors for applications such as monitoring
the performance of many lines or dial pulse detection/collection.
Monitoring of any E1 transmit or receive path with a frame pulse
provides a bussed test access for Channelized E3 or SDH applications
where an individual E1 signal is not directly available. Direct LIU
control by the microprocessor eliminates external components. The quad
framers and the octal framers support JTAG compliant boundary scan
(IEEE 1149.1) to simplify manufacturing testability.
According to Steve Lam, Product Manager at TranSwitch
Corporation, "With this announcement, we are rounding out our framer
family. When communications and networking system OEMs select
TranSwitch's framer products, they expect that these devices will

The key features of the devices include diagnostic, test and
maintenance functions, and the devices are also compliant with the
worldwide standards, ANSI, ETSI and ITU."
Design support packages for the entire framer lineup include
evaluation boards, reference designs, BSDL files, device drivers, and
full applications support from TranSwitch - all the essentials needed
to accelerate customers' time-to-market.
