+1-972-234-4343 - info@voxtechnologies.com Access Bank I Access Bank I Carrier-class Channel Bank Easily provision varied analog voice services from T1 Compact device converts digital services to analog circuits ® The Access Bank I is an economical, compact device for converting T1 digital access services to 12 or 24 individual analog telephone circuits. Six different types of 12-channel and 4+8 channel telephone line interface cards provide a variety of analog line services, including: • BRFXS • DPO • DPT • E&M • FXO • FXS • FXSDN • PLARD • SPOTS • TO The Access Bank I automatically adapts to changing line conditions, providing a clear, echo-free transmission path at all times. Minimize deployment time Designed for speedy deployment, the Access Bank I provides installation instructions right on the case. Configuration is done via DIP switches and self-test routines to ensure that all circuits are operable. The design incorporates an integrated CSU, allowing direct T1 line connection and monitoring. In-service maintenance capabilities include hot-swappable line cards, channel LEDs and fuseless ® protection of all interfaces. A remote management option with Windows GUI software and built-in modem is also available. Direct connection to full CLASS features The Access Bank I TR-08 option offers direct digital T1 connection to Class 5 local switch interfaces, eliminating the need for analog conversion of line connections at the Central Office. TR-08 signaling can be provisioned for physically separate shelves. Unlike trunk-side T1 switch connections, line-side TR-08 ® connections supply full CLASS features directly to customer phone lines.
