1 Scope/Field of application This document specifies a set of requirements for an ATU-R supporting different ADSL modes (e.g. ADSL2+). The specification aims to detail the basic connectivity requirements at the physical, ADSL, ATM and Ethernet level.

This document specifies the requirements for an ATU-R using multi-protocol encapsulation of bridge protocols over ATM over ADSL over PSTN.

All requirements in this specification assume that the ATU-R is configured in bridge mode. This does not prohibit the inclusion of additional functionality into the ATU-R, e.g. router or WLAN functionality.

The objective is to ensure full interoperability between equipment from different vendors. ATU-C and ATU-R from different vendors with different hardware chips shall be fully interoperable with each other.

Nokia D50 interoperability CPE 3001 The ATU-R shall be interoperable with Nokia D50e type of

DSLAM, with following line cards: eDMT8A3s, eDMT4f, eDMT8-1, eDMT8-2S

Figure 2 ADSL system reference configuration

Reference configuration: The equipment stationed at the customer premises consists of a POTS splitter and a modem designated ATU-R. The ATU-R could be stand-alone equipment or be a part of the Data Terminal Equipment (DTE). The DTE could e.g. be a PC or local area equipment such as a router. The local exchange (LE) equipment contains the ATU-C and a splitter. The ATU-C is the counterpart to the ATU-R. The LE equipment is often called DSLAM.

ATU-R: The term ATU-R is used when describing CPE functionality and performance.

ETSI FB: Line impairment type. Details can be found in Broadband Forum TR-067 [14] or in ETSI TS 101 388 [10].

ETSI Loop #1: Cable type. Details can be found in the ETSI TS 101 388 [10] or in the ITU-T Rec. G.996.1 [7].

ETSI Loop #2: Cable type. Details can be found in the ETSI TS 101 388 [10] or in the ITU-T Rec. G.996.1 [7].

Sync Time: Sync Time is the time interval from the moment when the modem starts Training, until the moment Showtime is achieved.

Showtime: The state reached after Training is completed and data can be transmitted.
