History
Paya Communication Industries 
(PCI) was founded in 1980 by a trio of young engineers seeking to design and 
manufacture electronic PABX systems. Since then the company has aggressively 
pursued its campaigns of growth.
PCI started to manufacture in 1981. From 1981 to 1988, the company solidified 
its well known brand CARIN. Various PABX models, branded under the name CARIN, 
were introduced to market and successfully grabbed the attention. These small 
capacity PABXes, served various small and medium sized businesses with 4 to 96 
extensions and 2 to 12 trunks.
Eight years of successful presence in PABX market was followed by a major step 
forward. In 1989, CARIN-500 was introduced. It was an innovative product 
enjoying stored program control (SPC) technology with a capacity to serve up to 
432 extensions. CARIN-500 could be equipped with 8 to 32 trunks. Its technical 
capabilities far exceeded customer needs. CARIN-500 was a total success.
In 1990, PCI started its manufacturing plant of 6’000 square meters in the 
eastern industrial zone of Tehran to answer the growing market demand.
Until 1991, PCI used its experience in CARIN-500 product to renovate its whole 
PABX product lines to take advantage of the established stored program control 
technology. 
The breakthrough came in 1992. PCI launched its modern new product line. In this 
year, CARIN-2000 was introduced to market. CARIN-2000 benefited a fully digital 
design based on TDM/PCM technology. CARIN-2000 proved to be what it was promised 
to be. Along with CARIN-2000’s introduction, PCI started its aggressive campaign 
to become a key player in public telecommunication sector.
In the same year by winning a large share of PTT’s international tender, PCI 
powerfully continued its way of success. In less than two years, PCI integrated 
tens of CARIN-2000 exchanges in telecommunication network and served 300’000 
subscribers. During this period, CARIN-2000 was installed in 150 towns and 
cities around the country including major cities like Tehran, Isfahan, Tabriz, 
Kermanshah, Zahedan, and Abadan. 
Until 1995, PCI established its strong brand image in the market but never 
missed any opportunity to innovate. In this year congruent with its growth 
strategy, PCI introduced CARIN-LX1, a high capacity exchange. CARIN-LX1 can 
serve up to 50’0000 subscribers with which PCI targeted high capacity exchange 
market.
In 1995, PTT held a one million line international tender. PCI won a large share 
of that tender to supply about 300’000 ports. In the next year, PCI once again 
contracted to supply 400’000 ports to PTT. 
In 1997, PCI extended its digital exchange product line with the introduction of 
CARIN-MX1. CARIN-MX1 can serve up to 6720 subscribers and was targeted for 
medium sized telecommunication centers. CARIN-MX1 was introduced to fill the gap 
between low and high capacity CARIN exchanges. 
During 1998 and 1999, PCI introduced various product lines including switching 
test equipments, digital access network equipments, pair-gain systems, and 
transmission systems. Among them, CARIN-UPG and CARIN-HDSL grabbed much 
attention very soon and both of them were successful.
At the turn of the millennium, PCI continued its way of success by expanding its 
market share. With an eye toward international market, PCI successfully 
penetrated some foreign markets. The company, alongside its manufacturing 
operations, has mobilized its resources to become one of the key players in GSM 
and wireless industry.
