VoIP / RoIP
Leased Line Replacement
The AVA-E allows provides an ethernet or serial transport replacement for analog leased lines (4-wire E&M, 2-wire FXS and FXO, and dedicated audio). It is one of the few analog voice adapters that provides full fidelity audio bandwidt with PCM and ADPCM to faithfully reproduce audio control tones, as well as low bit rate options for minimum bandwidth serial paths.

CIP-ALL
Leased Line Replacement
The CIP-ALL connects classical analog, voice frequency equipment through an Ethernet - IP Packet Network. Such equipment may have Leased Line or FXO / FXS POTS telephone interfaces sometime with embedded modems. The Circuit Emulation over Packet processor delivers high performance, extremely low latency, and a perfect distortion-free transport of the analog signals. The CIP-ALL provides many emulation protocols and a dual 10/100 BaseT and optical Gigabit Ethernet connectivity to adapt to any network requirement. Read more here.

AM-3440
Multiservice Access Device
The workhorse for supporting multiple analog lines via ethernet TDM and faster modes. An Integrated Access Multiplexer is equivalent to multiple T1/E1 channel banks rolled into a single chassis. Supports 4 or more T1/E1 interfaces, ATM/Frame Relay, has 12 DTE slots for FXS, FXO, E&M, serial DTE interfaces, IDSL, HDSL. SNMP GUI, telnet or serial configuration, and cross connect at the DS-0 level. Read more here.

Priority Audio Switch The Priority Audio Switch (PAS) is a small audio and PTT switch box that enables one dispatch station to override a second dispatcher. This maintains primary control of a transmitter with the priority dispatcher while allowing a second dispatcher, who may be remotely located, to operate the transmitter without any special switching. This is useful in airport control applications, remote two-way dispatching, and other audio applications where one audio source needs priority over a secondary source. Read more here.

PTT-24
Push-to-Talk Lockout Device
The PTT-24 is a Push-to-Talk lockout device. It is used with multiple E&M circuits linked to radios using T1 lines. The PTT-24 solves the problem of radio transmitters being locked into a Transmit ON state when a T1 circuit fails. Many T1 trunk lines will go into a busy condition when the T1 trunk fails. This causes the E&M leads to lock in an ON state, which causes radio transmitters to lock in the ON state. Read more here. Proudly manufactured in the United States of America

PTT-2
Push-to-Talk Lockout Device
Simliar to the PTT-24, the PTT-2 is a Push-to-Talk lockout device on a smaller scale. It is used with multiple E&M circuits linked to radios. The PTT-2 solves the problem of radio transmitters being locked into a Transmit ON state when a T1 circuit fails. Many T1 trunk lines will go into a busy condition when the T1 trunk fails. This causes the E&M leads to lock in an ON state, which causes radio transmitters to lock in the ON state. Read more here. Proudly manufactured in the United States of America.


Modem
Push-to-Talk Adapter
The DCB Push-To-Talk Adapter (PTT Adapter) is designed to control PTT in multi-drop radio applications. It's built into a RS-232 DB-25 adapter and is inserted between a modem and multi-drop radio system. Commonly used in SCADA applications with Motorola, MDS, GE, and other ISM band radios Read more here. Proudly manufactured in the United States of America.
