The UTEL 400ES LLU is a high performance Test Access Switch Module specifically developed for Local Loop Unbundling. When fully equipped, this compact unit can provide test access to 400 line circuits. It is designed with 16 individual cards with 25 line circuits on each. This gives the unit very high flexibility and expansion in stages of 25 circuits at a time.

This unit can be installed with just 1 card to introduce Test Access.

It can be rack mounted in a standard 19" frame or ETSI configured rack. Easy cable access to the rear of the unit and front loaded for access and expansion.

Cable connection is via industry standard 25 pair AMP Champ connectors. Male cable connectors are used for the incoming lines and female connectors are used for the outgoing lines.

This product is ideal for CSP's or operators offering Local Loop Unbundled access or service. The Switch Matrix can be easily expanded per shelf and then further by simply daisy chaining on extra switch modules in line with customer growth.
