Verilink Access System 2000: The Basics 1-3
AS2000 Design
The AS2000 system is designed to operate under the Telemetry
Asynchronous Bit Serial Protocol (TABS protocol) and the Advanced
Communication Protocol (ACP). TABS is an industry-wide
controller protocol. Verilink’s ACP is a faster and more powerful
protocol developed as a part of the Advanced Communication
Engine (ACE) architecture. AS2000 provides same-shelf integration
of TABS and ACP-based modules through the use of the Node
Controller Module (NCM 2000).
Advanced
Communications
Engine (ACE)
Verilink’s Advanced Communications Engine (ACE) architecture
supports international carrier channel standards, including E1, T1,
DS3, and ISDN Primary Rate Interface (PRI). The ACE architecture
uses the Advanced Communication Protocol (ACP) to communicate
between modules. The ACE architecture adds a cross-connect
switch, enabling individual Level 0 channels to be directed to a port
within a module, or to the port of another module within the node.
The ACE architecture transforms a shelf of individual modules into
a bandwidth manager.
