About the 5910 POTS Splitter

The 5910 is a double-density POTS splitter that separates the DSL (Digital
Subscriber Line) and POTS (plain old telephone service) frequencies. When
populated with 8 POTS splitter cards, it delivers 192 ports in 2U of a standard rack.
The 5910 provides make-before-break lifeline POTS. Whenever a card is removed
from the shelf, POTS service is uninterrupted, ensuring that critical services like
911 remain available to the end user.

With the emergence of ADSL2+ enhanced services like video, the POTS Splitter is
a vital part of the network. The innovative design of the 5900 series addresses
specific issues that affect video flow such as crosstalk and ring-trip problems. The
5900 Series is environmentally hardened to handle such locations as remote
cabinets as well as Central Offices.
