Page 1 of 4 Broadband Service Agreement-Attachment A DSL Service over the Fiber To The Curb (FTTC) Network in Richardson, Texas Southwestern Bell Telephone Company1 (“SWBT”), offers this Attachment A to cover the conditions of service for XDSL over the Fiber To The Curb (“FTTC”) network in Richardson, Texas for use by Competitive Local Exchange Carriers, (CLECs) and CLEC wishes to purchase such services from SBC-13STATE. 1. 1 Description of Infrastructure 1.1 The FTTC network deployed by SWBT in Richardson, Texas is a unique architecture consisting of an Optical Concentrator Device (OCD) in the Richardson central office, capable of DS3 or OC3c connection to the CLEC’s collocated location. The OCD passes ATM packetized signals over a dedicated, separate fiber facility from the voice side of the central office to the Remote Terminal, where an FTTC Host Digital Terminal device is housed. Optical Splitters on the back of the Remote HDT pass a digital signal further toward the end user location to an Optical Network Unit, this time via joint fiber with the voice path. The ONU will segregate the voice from the data, with a separate copper feed to the end user, for voice traffic and either a separate coaxial or copper feed for the DSL traffic both terminating at the Network Interface Device, (NID). As with other services, SWBT will not be responsible for Customer Provided Equipment (CPE), including but not limited to a compatible modem or inside wire. 1.2 Access to the XDSL over FTTC is provided under this Agreement where FTTC is deployed and operational and where facilities are available to serve a Residential End user served by the Richardson Central Office. Availability can be confirmed via utilization of the Verigate system On December 30, 2001, Southwestern Bell Telephone Company (a Missouri corporation) was merged with and into Southwestern Bell Texas, Inc. (a Texas corporation) and, pursuant to Texas law, was converted to Southwestern Bell Telephone, L.P., a Texas limited partnership, doing business as Southwestern Bell Telephone Company (“SWBT”).
