Installation and Warranty Notes for the
Cisco LRE 48 POTS Splitter
November 2002
This installation note provides instructions for installing the Cisco LRE 48 POTS Splitter with the
Catalyst Series of Long-Reach Ethernet (LRE) switches. (POTS is also known as plain old telephone
service.)
The Cisco LRE 48 POTS Splitter, also referred to as the splitter, is a set of filters that is used in installations
where LRE traffic shares the same telephone lines as existing voice, integrated services digital network
(ISDN), or Smart Phone services. The splitter separates the LRE traffic from the other telephone
services, sending the high-frequency LRE traffic to a Catalyst LRE switch and the low-frequency
telephone services to a private branch exchange (PBX) switch.
Note
Installation of a POTS splitter is only necessary if voice and data services share the same wire pair.
No configuration of the splitter is necessary. After connecting the devices to the splitter, the splitter
automatically separates the LRE and telephone traffic.
Caution
The Cisco LRE 48 POTS Splitter is a nonhomologated splitter that is not certified for connection to a
public switched telephone network (PSTN). Connecting the splitter directly to a PSTN can damage the
splitter and possibly any other equipment connected to it, such as LRE switches or LRE customer
premises equipment (CPE) devices. If telephone services will be sent directly to a PSTN, you must use
a homologated POTS splitter. Verify the regulations in your area or country regarding direct connections
to a PSTN. For more information about homologated POTS splitters, contact your Cisco sales
representative.

Description
Description
The Cisco LRE 48 POTS Splitter is a passive unit and does not require any power input. It provides the
separation of the LRE high-frequency signals and the low-frequency signals of the other telephone
services on the same telephone line. The splitter has these features:
Note
•
Supports 48 lines carrying LRE traffic and telephone services
•
Allows voice- and ISDN-band signals to pass through without interference from LRE data traffic
•
Isolates the very-high-data-rate digital subscriber line (VDSL)-based signals used to carry LRE
traffic from other telephone services
•
Provides six RJ-21 connectors to connect to up to two LRE switches (12 or 24 LRE ports each), a
PBX switch (48 ports maximum), and up to 48 Cisco LRE CPE devices
Cisco LRE products are designed to share lines with analog, ISDN, and digital private branch exchange
(PBX) switch telephones that use the 0 to 700 kHz frequency range. Digital telephones connected to
digital PBX switches that use frequencies above 700 kHz do not work when sharing a line with LRE
signals. Due to the proprietary nature of digital PBX switches, some digital PBX switch services use
frequencies above 700 kHz.
Figure 1 shows the Catalyst series of LRE switches that can attach to the splitter.

Cabling Recommendations
Connecting the splitter to a switch or patch panel requires a male-to-male RJ-21 cable, Category 3 or
above.You can order RJ-21 cables from your cable vendor, or you can order these cables from your Cisco
sales representative:
•
CAB-5-M120M120-5= (Category 5 cable with 90-degree, male-to-male RJ-21 connectors)
•
CAB-5-M180M120-5= (Category 5 cable with 120-degree, male-to-male RJ-21 connectors)
The screws that you need to secure the cable to the switch are shipped with the cable. Contact your Cisco
sales representative for more information.
Note
If you order cables from your cable vendor or decide to make cables yourself, refer to the “Connectors
and Cables” section on page 22.
Facing Cables in the Same Direction
If you decide to use cables that have 120-degree RJ-21 connectors, you need to decide whether the cables
face to the right, to the left, or from the middle of the splitter before you order them. (See Figure 10 and
Figure 11.) Some cables have large connectors and a thick coating around the cable. If they are not
installed in the same direction, they do not fit easily on the splitter connectors.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate
radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television
reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in
part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation.
However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class
A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct
any interference to radio or television communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco
equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by
using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television
or radio are on circuits controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.
