Broadband Service Agreement-Attachment A

DSL Service over the

Fiber To The Curb (FTTC) Network in

Richardson, Texas

Southwestern Bell Telephone Company (“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. Description of Infrastructure

1.1The FTTC network deployed by SWBT in Richardson, Texas is a unique architecture consisting ofan 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.

1.2Access 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 accessible for CLECs via the Toolbar. There are fifteen RT’s and over two thousand ONU’s deployed in this FTTC network infrastructure.

  1. Definitions

2.1Terms utilized above in Section 1.1 defining the FTTC Network are as follows:

2.1.1Host Digital Terminal (HDT): Equipment having two major subsystems, one for telephony, the other a FLX shelf providing ATM routing and multi-Plexing functionality. The voice and data are recombined via a multimode OC-3 signal to the FLX shelf and subsequently delivered to the ONU.

2.1.2Optical Network Unit (ONU): A pedestal type cabinet containing equipment capable of rearranging the light guide transmission signals onto Copper facilities leading to the end user’s residence. Capable of up to 16 broadband ports, maximum.

2.1.3Optical Splitter: Equipment placed in the RT, to pass transport signals onto fiber between the Remote Terminal and the Optical Network Unit. Can divide the signal 1x2 or 1x4, single mode, based on STII connectors.

  1. Service Description

3.1Except as otherwise provided herein, the terms, rates and conditions for Ordering XDSL over the FTTC network will be the same as those applicable to ordering the ADSL over the NGDLC under the Broadband Service, Data Service Configuration. XDSL service over the FTTC network will not be offered over the Combined Voice and Data option, but rather the Data Service Only option.

3.2The standard provisioning interval for XDSL service shall be seven (7) working days once an accurate LSR has been received.

3.3Sections 10, 11 and 13 of the Broadband Service Agreement shall not apply to the xDSL service over the FTTC network.
