If you are concerned about maintaining several critical telephone connections in your company, mobile command center or emergency center, consider the ML500D ™. This multiline system accommodates up to five "cellular lines" in a single compact rack-mountable chassis. The ML500D ™ can be installed as a stand-alone system or with your key system or PBX.

The CPE ^ONE ™ is designed for indoor installations in small offices or residences and is available with battery backup. It is used where a standard telephone line is not available. Because like all of our fixed cellular equipment the CPE ^ONE ™ provides dial tone, tip-to-ring and ring voltage, you can connect standard telephones, fax machines, and modems.

For backing up critical circuits in certain command and switching centers, we offer the CIUS™ (Cellular Interface Units) series of equipment. The CIUS ™ incorporates electronics and alarm functions to meet special requirements for installation in telephone company central offices and similar environments.

The Line Sensor module automatically switches TransTel single or multi-line equipment from standard telephone line to cellular when the telephone line has been cut or no dial tone is present.

The PentaLink Antenna Combiner ™ couples up to five cellular transceivers to a single antenna.
