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
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
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.
Figure 1 LRE Installation Example
Note Digital telephones connected to digital PBX switches that use frequencies above 700 kHz do not work when sharing a line with LRE signals. (CSCdu73260)
Note If the building does not use a PBX switch and telephone services are sent directly to an outside PSTN, you need to provide a homologated POTS splitter instead of the Cisco LRE 48 POTS Splitter. For more information about homologated POTS splitters, contact your Cisco sales representative.
The splitter has 48 internal ports and, through 6 RJ-21 connectors, connects to the LRE switches, the PBX switch, and a patch panel or wiring bundle. Two RJ-21 connectors on the front of the splitter connect to the LRE switches. Figure 2 shows the front panel of the splitter.

If the splitter will be connected to two LRE switches, we recommend mounting the splitter between the two switches. (See Figure 8.)
Figure 8 Mounting the Splitter in a Rack Between Two LRE Switches
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.
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.
Figure 9 Connecting the Wiring Trunk Cables (Front View)
Figure 10 Connecting the Wiring Trunk Cables (Rear View)
Securing Cables
Each cable must be secured to the splitter by one of these methods:
•For a 90-degree connector, use two screws. (See the top of Figure 11.)
•For a 120-degree connector, use a screw and a cable tie. (See the bottom of Figure 11.)
Note The cable tie is not included with the connector and cable assembly.
Figure 11 Securing a Cable to the Splitter
Connecting to LRE A, PBX A, and LINE A
Ports 1 through 24 of the splitter connect to the LRE A, PBX A, and LINE A connectors. To connect these ports to a Catalyst LRE switch, PBX switch, and patch panel, follow these steps:
Step 1 Connect one end of a wiring trunk cable (not included) to the LRE A connector on the front of the splitter. (See Figure 12.)
Figure 12 Connecting LRE A to an LRE Switch
Step 2 Connect the other end of the wiring trunk cable to the LRE port on the front of the LRE switch.
Step 3 Connect one end of another wiring trunk cable (not included) to the PBX A connector on the rear of the splitter. (See Figure 13.)
Figure 13 Connecting PBX A to a PBX Switch
Step 4 Connect the other end of the wiring trunk cable to the PBX switch.
Step 5 Connect one end of another wiring trunk cable (not included) to the LINE A connector on the rear of the splitter. (See Figure 14.)
Figure 14 Connecting LINE A to a Patch Panel
Step 6 Connect the other end of the wiring trunk cable to the patch panel or wiring bundle that connects the LRE CPE devices 1 through 24.
You do not need to configure the splitter. The splitter now separates the high-frequency LRE data from the low-frequency telephone services on ports 1 through 24, sending the LRE traffic to the LRE switch and the other telephone services to the PBX switch.
Connecting to LRE B, PBX B, and LINE B
Ports 25 through 48 of the splitter are connected to the LRE B, PBX B, and LINE B connectors. To connect these ports to an LRE switch, PBX switch, and patch panel, follow these steps:
Step 1 Connect one end of a wiring trunk cable (not included) to the LRE B connector on the front of the splitter. (See Figure 15.)
Figure 15 Connecting LRE B to an LRE Switch
Step 2 Connect the other end of the wiring trunk cable to the LRE port on the front of the LRE switch.
Step 3 Connect one end of another wiring trunk cable (not included) to the PBX B connector on the rear panel of the splitter. (See Figure 16.)
Figure 16 Connecting PBX B to a PBX Switch
Step 4 Connect the other end of the wiring trunk cable to the PBX switch.
Step 5 Connect one end of another wiring trunk cable (not included) to the LINE B connector on the rear of the splitter. (See Figure 17.)
Figure 17 Connecting LINE B to a Patch Panel
Step 6 Connect the other end of the wiring trunk cable to the patch panel or wiring bundle that connects the LRE CPE devices 25 through 48.
The splitter now separates the high-frequency LRE data from the low-frequency telephone services on ports 25 through 48, sending the LRE traffic to the LRE switch and the other telephone services to the PBX switch.

Technical Assistance Center
The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available: the Cisco TAC website and the Cisco TAC Escalation Center. The type of support that you choose depends on the priority of the problem and the conditions stated in service contracts, when applicable.
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 Cisco TAC website provides online documents and tools to help troubleshoot and resolve technical issues with Cisco products and technologies. To access the Cisco TAC website, go to this URL:
http://www.cisco.com/tac

http://www.cisco.com/tac/caseopen
If you have Internet access, we recommend that you open P3 and P4 cases online so that you can fully describe the situation and attach any necessary files.
Cisco TAC Escalation Center
The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.

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.
