QWEST® MOE is a Layer 2 intelligent Ethernet switching service that offers enterprise and carrier customers the ability to interconnect standard LAN interfaces between customer locations in designated Qwest Wire Centers where facilities are available. The Qwest interface to the customer will be standard metallic, single-mode fiber and multi-mode fiber facilities

Central Office Bandwidth Profile is a MOE offering that originates and terminates in the same central office for use with SST, GeoMax and SHNS Ethernet Ports. This Bandwidth Profile can also be used for Collocation. Locations where Central Office Bandwidth Profile is available are listed in attachment 1.

Ethernet with Extended Transport (EwET) Bandwidth Profile offers MOE outside the designated MOE service area (listed in attachment 1) via EwET using the EwET customer interface. A Company-provided DS3 as described in Section 7 PRIVATE LINE ACCESS SERVICE, is also required.

Qwest MOE service offers the following IEEE 802.3-2002, Carrier sense multiple access with collision detection (CSMA/CD) access method and physical layer specifications standard UNIs.  Not all UNIs available on copper facilities:

10Base-T ports - 10 Mbps full duplex Local Area Network interface over two pairs of twisted-pair telephone or Category 3, 4 or 5 (recommended) copper wire with a RJ-45 connector

100Base-TX ports - 100 Mbps full duplex Local Area Network interface over two pairs of Category 5 Unshielded Twisted-Pair (UTP) or Shielded Twisted-Pair (STP) copper wire with an RJ-45 connector

1000Base-T ports - 1000 Mbps full duplex Local Area Network interface using four pairs of Category 5 balanced copper cabling with a RJ-45 connector

1000Base LX ports - 1000 Mbps full duplex Local Area Network interface using Long Wavelength (1310 nm) lasers over one pair of Single-Mode Fiber (SMF) with a duplex FC-PC connector

1000Base SX ports - 1000 Mbps full duplex Local Area Network interface over one pair of Multi-Mode Fiber (MMF) – Implementation Date: No earlier than 11-09-04

Qwest will place an ethernet terminal at the End-User premises for User-Network Interfaces (UNIs).  Customer traffic will be transported from each UNI to a Qwest Central Office (CO) core switch using a rate-limited Network Access Link (NAL).  NALs are available in customer-specified bandwidth increments from 5 Mbps up to 1 Gbps.  The physical UNI as well as NAL bandwidth can be different at each location.

The Metro Optical Ethernet network between customer locations is not dedicated to one user but shared between multiple customers.  Virtual LANs (VLANs) are used by Qwest to separate customers’ traffic over the shared network. VLANs will conform to the IEEE 802.1Q standards.

Qwest MOE Service Points are geographic locations, designated by Qwest, where the MOE network can be accessed. Customer premises with a Serving Wire Center that is not designated as a Qwest MOE Service Point will not be able to connect to the Qwest MOE network.  The list of Metro Optical Ethernet Service Points can be found in Attachment 1.

Qwest® Metro Optical Ethernet Services are offered under tariff in the locations identified in Attachment 1.

• Qwest will manually provision the speed and full duplex transmission mode on all 10/100/1000 Mbps MOE customer facing switch ports.  Auto-sensing and auto-negotiating will not be supported at the UNI.
• Multiple interfaces using IEEE 802.3ad Link Aggregation or, 802.1d, 802.1w Rapid or 802.1s Multiple Spanning Tree Protocol for increased bandwidth and/or link redundancy/load balancing are currently not Qwest MOE service options at the UNI. 
• The UNI associated with Qwest Metro Optical Ethernet for LAN interconnection will not provide the repeater functionality as described in IEEE 802.3-2002.
