All products share a common operating system, CLI syntax, web UI, and SNMP MIBs. In all

cases, 802.1Q VLANs and QoS can be managed through the entire network from the core switch

to each remote Ethernet port.

An important feature in common with all products is line power. The remote client device (also

called a CPE) is line powered from the core switch installed in a central wiring closet. Pay close

attention to the difference in line power function for each product.

Simple Network Topology

In the diagram above, components of the network topology are:

Motorola Switch. This is the “concentrator” installed in a central wiring closet. Each

product family has a different switch port density. The Switch provides the management

interface for all features on the remote CPE.

Motorola CPE. Although the term CPE is not used in Motorola product literature, this is a

common term in the industry for this device. Unlike other “CPE”s however; the Motorola

CPEs operate by line power, and provide advanced features to enable enterprise

services. In the T3 product family; CPEs are called WallPlates, to match the form factor

of the product design.

Upstream Ethernet network. Each Motorola Switch (A) has 1, 2 or 4 Ethernet uplink

ports; either 10/100Mb, or 10/100/1000Mb. Use these ports to connect to the core

network.

Premises wiring. The premises wiring must be UTP - unshielded twisted pair. In the

case of T3; a single wire pair is required, and can be shared with analog telephone

service. XLP-6800 requires two or four wire pairs, not shared with analog telephone

service. XLP-7000 also cannot be shared with analog telephone, but requires only one

wire pair for operation. The maximum distances over premises wiring is:

T3 PowerBroadband: up to 600m (2000ft)*

XLP-6800 Extended PoE: up to 3000m (10,000ft)

XLP-7000 Extended PoE: up to 1500m (5,000ft)

*600m is the limit of line power. If using an optional external power supply, T3 will deliver

broadband up to 1500m

Dowstream Ethernet network or Ethernet devices. XLP (extended line power) products

provide 802.3af compliant PoE power on the downstream ports. Connect devices such
