RADIO DISPATCH CONSOLES
At most communications centers is a radio console through which most communications with field units flow. Zetron consoles interfaces with radios, logging recorders, telephones, paging encoders, intercoms and other essential dispatch-related equipment. For simple operations, Zetron offers the self-contained, 12-channel Model 4010

Radio Dispatch Console and for more complex dispatch requirements, consider the flexibility and capacity of the Series 4000 Communications Control System

that can go up to 16 consoles (including video consoles) and 48 channels.

VOIP RADIO DISPATCH CONSOLE
Zetron’s pure, end-to-end Voice over IP (VoIP) radio dispatch console is built upon the widely accepted Session Initiation Protocol (SIP) open Standard. The system consists of PC operator positions running application software and series 6000 SIP Radio Gateways (SRGs)

. The connection between the operator positions and gateways is a IP Local Area Network (LAN) or Wide Area Network (WAN). The architecture of the console system makes it inherently distributed, eliminating the requirement to concentrate equipment in a single, vulnerable site. Version I of the system supports simultaneous connection to 20 radios and 6 PC operator positions, with option for use a LCD touchscreen monitor.

DESKTOP CONTROLLERS (REMOTES)
Sometimes, an operator needs to communicate with radio users in the field, but finds it`s impractical to place a radio base station right on the desktop. A Zetron tone remote is an attractive desktop instrument that allows an operator to control a base station from any distance using inbuilding wiring or a leased line. Zetron offers Model 280 Digital Tone Remote

where multiple operators need to share the same base station and Model 284 Multi-Line Tone Remote

that allow an operator to select between up to four base stations and specially for LTR^® and iDEN^®^TM trunked radio systems Zetron's remotes and Model Z370 iDEN-compatible Remote

INTERCONNECT, TONE PANELS & REPEATER MANAGERS
Zetron is the world leader in interconnect technology. Interconnects allow people with mobile or handheld radios to place or receive phone calls into the public telephonw network. Model 30 WorldPatch

is an advanced but low-cost single user (simplex or half-duplex) interconnect, Model 35 A Microconnect

is a single user interconnect that supports simplex, half and full-duplex operation, Model 45B Z-Patch

is a two-line, programmable interconnect for multiple groups of users, Model 48Jr Repeater Patch

is an economical, one-line interconnected repeater panel also for multiple groups and Model 48-MAX Interconnected Repeater Panel

can recognize and provide service to up to 750 individual radio users.
Zetron's tone panels and repeater managers are equipped with ToneLock, an exclusive decoding circuit that holds onto a weak CTCSS/DCS even if the signal drops below 3 dB SINAD. Ask for Model 37 Repeaterman

, Model 37-Max Repeater Pal for up to 154 users

, Model 38 A Repeater Panel

and Model 38-Max
