About the 5920 POTS/ISDN Splitters
The 5920 POTS/ISDN splitters separate the DSL (Digital Subscriber Line) and
POTS (plain old telephone service) or ISDN (Integrated Services Digital Network)
frequencies. The 5920 POTS/ISDN Splitter chassis holds from two to 18
POTS/IDSN splitter cards, each of which supports 24 DSL subscriber lines:
The 1U Model 5920-B1-048 supports 2 cards and 48 DSL subscriber lines
The 3U Model 5920-B1-144 supports 6 cards and 144 DSL subscriber lines
The 4U Model 5920-B1-192 supports 8 cards and 192 DSL subscriber lines
The 9U Model 5920-B1-432 supports 18 cards and 432 DSL subscriber lines
The 5920 POTS/ISDN splitter shelf was specifically designed to fit the dimensions
of an ETSI rack and meets the standards for EMEA markets. With front mount
connectors, 5920s can be mounted back to back or against a wall, eliminating the
need for swing shelves.
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.
