The UTEL TASM100ES MK11A Test Access Switch Module has been designed using the latest relay technology. Ideal for copper lines. 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, making the whole installation process very simple.

The Switch Matrix can be easily expanded by simply daisy chaining on extra switch modules in line with line growth.

UTEL can also supply custom made racks capable of holding 14 or 16 100ES TASMs, depending on the configuration, set up and location of Test Heads.

Additional back to back racks allow for very easy expansion. Simply add more TASM units as the customer base expands.
Daisy chain up to 12,800 line circuits per intelligent switch module controller.
