LPF-200 Series ADSL POTS Splitters
The ADSL NID POTS Splitter solutions meets most indoor and outdoor
requirements for single-line applications. Packaged in the standard
Keptel® Line Module footprint, we have developed a solution that
easily fits into most NIDs as a CPE device. The module occupies only
one position within the NID and is housed in a plastic shell and
encapsulated to provide an environmentally sealed product. All direct
inside wiring connections to the module interface to colored, plastic
coated washer screws.
Features:
• Single width line module footprint is space efficient
• Environmentally sealed
• Same splitter used with adjunct box applications reduces inventory
• Installs in a variety of NIDs
• Quick mounting capability in front of or behind existing indoor
wall jacks without drilling mounting holes or replacing existing phone
jack
• Low voice band insertion loss and flat voice band attenuation
distortion
• Compatible with both CAP and DMT
• Meets the ANSI T1.413 Annex E, ITU-T 992.1 Type 2 North American
and Telcordia™ requirements
Radio Frequency Interference Filter (RFI)
The Radio Frequency Interference Filter (RFI-P) is customer premise
installed inside the Station Network Interface. It is designed to
block unwanted RF energy as well as bypass RF energy to earth ground,
while remaining transparent to normal loop signaling and test
voltages. Using the earth ground connection, this filter acts like a
drain: providing a path to ground for the RF energy to bleed off the
phone line from both the network and customer side of the network
interface. It effectively eliminates all common mode and differential
mode RF interference induced on the phone line in the vicinity of the
RFI-P filter.
Features:
• Suppresses RF interference across AM, FM, CB, VHF,
TV, Amateur and UHF band
• Maximum suppression occurs in the AM band
• Bypasses unwanted RF energy to earth ground
• Excellent balance between Tip and Ring
• Eliminates all common mode and differential mode RF interference
• Designed for use in outdoor or indoor Network Interface Devices at
the customer premise
• Transparent to normal loop signaling and test voltages
Half Ringer Equivalent Circuit
The Keptel® Half Ringer Equivalant Circuit allows automatic or
manual testing to be performed from the central office without
interrupting service to the customer. The Half Ringer, when connected
in parallel with the phone line, poses a 0.5 REN load. The Half Ringer
is available in three different packages for both indoor and outdoor
use and can be used in a variety of applications. Factory installation
in a number of Network Interfaces Devices is available, please consult
AFL Customer Service for specifics.
Features:
• Available in a variety of packaging
• 0.5 Ringer Equivalance
• Installed parallel to the line
• Versions available for indoor or outdoor (ruggedized) use
