Two types of E1/ISDN cables are available:
❐
Aculab E1/ISDN
❐
Promptus E1/ISDN
Aculab E1/ISDN
An Aculab E1/ISDN cable connects one of these Aculab
E1/ISDN modules to an E1 or an ISDN PRI network:
❐
Single-interface with one 9-pin D-shell male
❐
Dual-interface with two 9-pin D-shell males
❐
Dual-interface with two 9-pin D-shell males for use
with an ETS300 network
❐
Single-interface with two BNC coaxial jacks
❐
Dual-interface with four BNC coaxial jacks
Single- and Dual-Interface D-Shell Cable
An LIU ships with each D-shell-compatible E1/ISDN
module. The LIU connects between the module and the
network and provides high-voltage isolation and
electromagnetic-compatibility circuitry.
Caution
You must use the LIU. Connecting network
equipment directly to the E1/ISDN module can damage
the module and the equipment.
