Carrier Access Channel Bank

The Carrier Access Channel Bank sets a new standard for connecting T1 switched services to Hybrid / Key and PBX telephone systems.  The Carrier Access ABI Channel Bank converts a T1 digital access line to 12 or 24 analog telephone circuits.  The Carrier Access ABI Channel Bank provides the most economical, compact, and reliable solution on the market for converting T1 digital access services to standard "dial tone" interfaces.  Business and government offices can connect their existing telephone systems to T1 digital services - without a significant investment in equipment.
 
One or two 12-channel telephone line voice cards plug into the LIU card to make a complete I Channel Bank.  The most commonly used 12-channel voice card is the FXS-12.  One FXS-12 card provides 12 standard Loop Start or Ground Start telephone line connections to a customer's telephone system.  The second FXS-12 card (for 24 telephone lines total)  can be added to the I Channel Bank simply by sliding it into the back of the cabinet.  
 
Using state-of-the-art solid state integrated circuits, ultra-reliability and advanced services features have been engineered into the Carrier Access ABI Channel Bank.  Only three circuit cards make up a complete 24 channel bank.  The FCC-registered T1 Channel Service Unit (CSU), Ringing Generator, Power Converters, Ringback Tone Generator, and Channel Bank Controller are all integrated into a single small electronics card called the Line Interface Unit (LIU).  The LIU connects directly to carrier T1 lines and supports selectable T1 standards of D4 or ESF framing and EMI or B8ZS line coding.  A quick field replacement of the LIU completely changes all common electronics in the Access Bank.
