The Quad T1/E1 ATM LIMO is a physical layer interface that provides support
for virtually any ATM application requiring T1 or E1 interfaces. The product
is a single-board subassembly that includes all the hardware and software
necessary to terminate four T1 or E1 facility interfaces, recover the clocks,
and access the ATM cells within the payloads. The facility cables connect
to the module via adapter cards, allowing the user to use RJ-48, BNC, or
Bantam facility connectors. To ensure compatibility with the network, the
product generates and monitors the T1 or E1 frame and ATM cell overhead.
The Quad T1/E1 surveillance, performance monitoring with continuous accumulation
and maintenance of facility and network performance statistics are all standard
features with the product.
