Installation and Warranty Notes for the
Cisco LRE 48 POTS Splitter
May 2003
This document provides instructions for installing the Cisco LRE 48 POTS Splitter with the Catalyst
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
You only need to install a POTS splitter 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 high-frequency LRE signals and the low-frequency signals of the other telephone
services on the same telephone line. The splitter has these features:
•
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
Installation and Warranty Notes for the Cisco LRE 48 POTS Splitter

Description
The splitter is supported by these LRE switches:
•
Catalyst 2912 LRE XL—4 fixed autosensing 10/100 ports and 12 LRE ports
•
Catalyst 2924 LRE XL—4 fixed autosensing 10/100 ports and 24 LRE ports
•
Catalyst 2950ST-8 LRE —8 LRE ports, 2 small form-factor pluggable (SFP) module slots, and 2
fixed autosensing 10/100/1000 ports
•
Catalyst 2950ST-24 LRE —24 LRE ports, 2 SFP module slots, and 2 fixed autosensing 10/100/1000
ports
These limitations and restrictions apply when you use the Cisco LRE 48 POTS Splitter with
Catalyst 2950 LRE switches and Cisco LRE CPE devices:
•
The Catalyst 2950ST-8 LRE switch, the Catalyst 2950ST-24 LRE switch, the Cisco 575 LRE CPE,
and the Cisco 585 LRE CPE are designed to share lines with analog, ISDN, and digital 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.
•
You can use a Cisco LRE 48 POTS Splitter with a Catalyst 2950ST-8 LRE switch, a
Catalyst 2950ST-24 LRE switch, a Cisco 575 LRE CPE, and a Cisco 585 LRE CPE.
•
The Cisco LRE 48 POTS Splitter does not support the Catalyst 2950ST-24 LRE 997 switch and the
Cisco 576 LRE 997 CPE.
In a typical installation, the splitter is attached to one or two LRE switches, the PBX switch, and a patch
panel or wiring bundle connecting to several Cisco LRE CPE devices that are installed in rooms of a
multidwelling tenant building. Figure 1 shows an example of an installation with 1 LRE switch, 12 LRE
CPE devices, and 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 26.
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 9 and
Figure 10.) 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.

Obtaining Technical Assistance
We categorize Cisco TAC inquiries according to urgency:
•
Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities,
product installation, or basic product configuration. There is little or no impact to your business
operations.
•
Priority level 3 (P3)—Operational performance of the network is impaired, but most business
operations remain functional. You and Cisco are willing to commit resources during normal business
hours to restore service to satisfactory levels.
•
Priority level 2 (P2)—Operation of an existing network is severely degraded, or significant aspects
of your business operations are negatively impacted by inadequate performance of Cisco products.
You and Cisco will commit full-time resources during normal business hours to resolve the situation.
•
Priority level 1 (P1)—An existing network is “down,” or there is a critical impact to your business
operations. You and Cisco will commit all necessary resources around the clock to resolve the
situation.
Cisco TAC Website

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.
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.
