*Qwest announces the availability October 24th, 2009 of 100Base-LX10/FX and
1000Base-ZX, where available as well as Gigabit Ethernet over STS-3c-2v and STS-3c-3v along with other VCAT Group mapping enhancements and support for the Tellabs 7100 OTS.

Qwest currently offers STS-1 electrical as well as OC-3, OC-12, OC-48 and OC-192 1+1 & 0X1 Linear interfaces delivered from Fujitsu and Nortel standard OC-3, OC-12, OC-48 and OC-192 SONET Add-Drop Multiplexers (ADMs) as well as Fujitsu and Cisco Next Generation SONET Hybrid (ADM/DCS) equipment.  Tellabs STS-1 electrical interface provided via the Titan 5500 Wideband Digital Cross-connect System (DCS) along with standard DS1 and DS3 interfaces including VT Transmux – DS3 and STS-1 are also supported.

Additionally available are:

• TL1 over 1) 3-layer X.25 (DTE or DCE mode) at 9.6 Kbps (or greater) and 2) TCP/IP 10/100Base-T Ethernet serial interfaces.  These OS management interfaces are limited to SHNS ACCU-Ring and Software Reconfiguration Capability (SRC) applications only.
• Point-to-point, bidirectional Data Communications Channel (DCC) tunnels on standard SONET Optical Carrier (OC-3/12/48/192) Network Interfaces delivered from Cisco Next Generation SONET ADMs.
• Point-to-point, bidirectional, full duplex 10Base-T, 100Base-TX , 1000Base-LX (Single-Mode Fiber only) and 1000Base-SX Ethernet over SONET Network Interfaces on SST and SHNS.
• 1+1 OC-3, OC-12, OC-48 and OC-192 UPSR interfaces delivered from Fujitsu and Cisco Next Generation SONET Hybrid (ADM/DCS) equipment.
• SONET Network Interfaces with the following embedded Ethernet payloads:

These SONET, corresponding OS management, DCC tunnels and Ethernet over SONET interfaces are/will be available in Arizona, Colorado, Idaho, Iowa, Minnesota, Montana, Nebraska, New Mexico, North Dakota, Oregon, South Dakota, Utah, Washington and Wyoming.  Determination is on an Individual Case Basis (ICB) for each customer request, dependent upon where equipment and facilities are available.

Qwest’s SONET-based services are offered under interstate and intrastate tariffs.

1) The SONET standards designate some bits and bytes in the overhead as undefined or unused.  Any interfaces offered as a part of Qwest’s SONET-based services employing nonstandard usage of these bits and bytes must be disclosed.  Vendor specific variations from the ANSI and Telcordia Technologies standards for STS-1 electrical and SONET Optical Carrier Linear interfaces are as indicated below for Alcatel-Lucent, Fujitsu, Nortel, Cisco and Tellabs NEs.
