Comma iTA
Overview
Comma iTA is a flexible and comprehensive telephony interface solution for Asterisk based PBX, Contact Center and Gateway installations.
Asterisk telephony applications, built on commodity computer servers, couple with Comma iTA’s via a standard Ethernet interface and an efficient TDM over Packet transfer protocol. The Asterisk server thus becomes a pure network appliance.
The Comma iTA provides dedicated voice processing hardware thus off-loading critical, channel related processing from the host server, while providing integration to legacy telecom infrastructure.
The Comma iTA thus supports the deployment of large, feature-rich solutions over a distributed and scalable architecture. It is possible to combine multiple iTAs and/or multiple servers in a single system
Features
- 1U rack-mount unit supports high density installations
- All the flexibility and features of Asterisk™
- Echo cancellation for all channels
- Timing synchronization of multiple units and host servers over Ethernet
- 10/100Base-T Ethernet connection to host server
- FXS interface options: up to 32 ports in steps of 4
- FXO interface options: up to 32 ports in steps of 4
- BRI (S/T), up to 8 ports, in steps of 4
- Echo Cancellation: Comma iTA provides dedicated hardware for echo cancellation, ensuring toll-quality speech in all situations
- Synchronization: Comma iTA provides dedicated synchronization hardware supporting timing recovery from the Ethernet or the ISDN interfaces. Multiple iTA’s and host servers can be synchronized to a selected clock source, eliminating the slips that disrupt fax and modem signals
- Extremely cost effective solution for many applications
Administration
- Management: Comma Proxy Manager (CPM) resides on Asterisk host and manages one or more attached Comma iTA’s
- Configuration: Configuration files and firmware image reside on Asterisk server and are sent to Comma on startup
- Status: Status is monitored by CPM and status changes are logged
- Field Upgrade: Firmware upgrade by changing image on host server and configuration file. Programmable Hardware upgrade by download and upgrade over network
Benefits
- Cost effective – compared to similar PCI-based adapters or external Gateway devices
- Expandable platforms – seamless via connecting additional Comma iTA devices to LAN.
- Distributed deployments – over Ethernet LAN infrastructure & TDMoIP or TDMoE transport
- Robust design – hardware includes power cross and secondary surge protection devices
- Hot swap – reduce platform down time. Replacing Comma iTA’s is quick and painless as Comma iTA firmware and configuration is stored on the server only. No need to replace PCI cards!
