New Mitel Chip Delivers Best-in-Class Reliability for
Caller ID: * Helps protect personal privacy: * Exceeds
Bellcore 'speech immunity' specifications
OTTAWA, CANADA--Mitel Semiconductor, a division of Mitel
Corporation (TSE: MLT; NYSE: MLT), is building on its leadership
position in Caller ID chips with a new integrated circuit that
exceeds the benchmark performance specifications that define
best-in-class reliability in Caller ID equipment.
Mitel's high-performance MT88E46A is a Caller ID (CID) and Caller
ID on Call Waiting (CIDCW) receiver chip that is used in corded
and cordless telephones, Internet phones, answering machines,
caller ID adjuncts and computer telephony integration (CTI)
Popularity of Caller ID Quadruples
According to a 1999 Arbitron NewMedia Pathfinder study*, 40
percent of U.S. households now have Caller ID, up from only nine
percent in 1995. Consumers were initially reluctant to use Caller
ID services because of concerns about personal privacy. But with
the proliferation of telemarketing, they now view Caller ID and
Caller ID on Call Waiting as services that protect personal
privacy and family time. Responding to demand, telephone
companies are now offering such services as anonymous call
rejection, call privacy, and priority call handling.
Mitel has demonstrated leadership in the Caller ID market since
1995, when it was first to integrate the CID and CIDCW functions
on a single silicon integrated circuit. The company now offers a
family of devices that address the requirements of this
'Mitel's leadership is based on applying mixed-signal technology
to increase performance and reliability in caller ID equipment,'
said C.P. Fu, product manager, Analog Signal Processing
Components, Mitel Semiconductor. 'Our new device is a low-cost,
high reliability solution that enables telephone companies to
offer hassle-free call management services.'
Human speech interferes with the ability of Caller ID on Call
Waiting equipment to properly detect or interpret the CPE Alerting
Signal (CAS) of an incoming telephone call. When interference
occurs, conversation is momentarily interrupted, or Caller ID
information is not sent to the user. Thus, Caller ID circuits
must be 'immune' to speech. Mitel exceeded Bellcore's (now
Telcordia) speech immunity performance specifications by
developing a patent-pending CAS detector.
Single-Chip Device Reduces Cost
The MT88E46A contains all of the circuitry required for a complete
physical layer solution, including a Bellcore-compliant CAS
detector, 1200 baud Bell 202/CCITT V.23 FSK demodulator, and
simple microcontroller interface. With two input op-amps, the
MT88E46A allows connections to both Tip/Ring, and the telephone
hybrid or speech IC receive pair, for optimal CIDCW
implementation. The superior CAS detector dramatically reduces
false signal detection (a condition known as 'talkoff') and signal
non-detection ('talkdown') problems.
The device also incorporates power-management functions, including
power-down for the FSK, CAS, or full-chip when required. The
MT88E46A is suitable for applications using a fixed power source
(with a +/-10% variation) between 3 and 5V. Mitel provides an
evaluation kit and application note to ease system development.
Pricing and Availability
The MT88E46A is packaged in a 20-pin SOIC with tape and reel
option. The device is now in full production. Pricing is US
$1.39 in 100K unit quantities.
