8. 142X CPEs and TDM productsInteroperability SHDSL productsThe table below shows the use of the following CPEs with TDM products:1421 SHDSL Router (including 3DES versions)1423 SHDSL1423 SHDSL 2ETH-4P1423 SHDSL 2ETH-4P HWAImportant note: The 1423 SHDSL and 1423 SHDSL 2ETH -4P versions support the HDLC, PPP and FrameRelay protocols on the SHDSL interface and accordingly are interoperable with TDM products as of PCB 0.1Level 3 hardware and T2863/00700 firmware. The 1423 SHDSL 2ETH -4P ISDN-2BRI HWA version NEVERcan be used with a TDM product at th e other side of the line.Set-upInteroperability issuesGeneral requirements: One needs at least firmwarerelease T2136/00800, T2145/00100 or T2141/00100 onthe Crocus SHDSL. On the Crocus SHDSL, configureline/eocChannel = itu-G.991.2.On the 1421 / 1423 configure line/timingMode =plesiochronous.The line speed is between 192 and 2048 kbit/s per linepair. For 2P operation with G703 interface or externalclock, one needs minimum firmware release T2141/00300on Crocus SHDSL.Notes: One needs minimum firmware release T2852/00600on the 1421.This combination does not work when a CrocusRouter 10M Interface is used on the Crocus SHDSLand ATM WAN encapsulation is configured over thelink. In case of a serial or LAN interface on CrocusSHDSL, one can also configure synchronous timingmode. In that case line pair speeds between 64 and2304kbit/s are possible.On the 1421 / 1423, configure line/timingMode =plesiochronous.Line between 192 (384 for 2P) and 2048 kbit/s. Userspeeds below 192kbit/s per line pair as of firmwareT2148/00400 on Crocus SHDSL G703 and T2852/02100on the 1421.Only possible with 1421 / 1423 as remote unit. On the1421 / 1423, configure line/timingMode = plesiochronous.Line and user speeds are between 192 and 2048 kbit/s.OneAccess Version 4.4 - 22 January 2008 10 / 14
