Legacy Systems Adds, Moves, Changes, Repairs and Phone Carrier Line Moves

​​​​The NEC DSX and SL1100 systems can utilize the older Category-3 cabling that are in place at buildings that have been cabled over 15 years ago and are not dependent on computer connections for outside or extension calls.


Cougar Telecom also services many of the older telephone systems including but not limited to Comdial, Panasonic, Nortel and Toshiba. Switching from one phone company to another? We can help. Call us for any legacy telephone system needs.

Innovation starts with the sleek DSX telephones. The 22-button telephone has a thin, floating design, two position angle adjustment for effortless viewing, and built in wall mounting. The 22-Button Display offers 12 programmable buttons, 10 speed dial buttons, a large 3-line-by-24 character display, four interactive soft keys, and a built in speakerphone.

The DSX-40 is a compact unit which starts as a 4 line, 8 digital station and 2 analog station system capacity. Expansion boards increase its capacity to accommodate up to 8 telephone lines and 24 digital stations. The built-in 2-port analog card allows the use of standard telephone devices such as credit card readers, FAX machines or standard analog cordless phones.
