Hello guys,

I am trying to configure a shdsl module but I don't get to up the Atms interfaces created. I think is a wire problem because I see the following message when the show controller shdsl command.

Hello Oscar and Patrizio,

it can be a cabling problem.

this SHDSL controller uses 4 wires out of or 8 wires.

so pairs 0,1 makes the first SHSDL link

pairs 2, 3

shdsl 4-wire mode enhanced

So actually if the external connector is an RJ-45 all 8 wires are to be used.

So check the cable you are using:

If you have an NT I should try to use an RJ-45 straigh cable (like a LAN cable)

if you have multiple NTs you may need to build a custom cable.

a reference doc is

http://www.cisco.com/en/US/docs/ios/12_4/interface/configuration/guide/h4wire.html#wp1052661

Hope to help

Giuseppe

Hello Giuseppe,

i'm using a cable built this way :

Router Telco

RJ45 RJ11

6

line0 5 ------ 4 cp1

line0 4 ------ 3 cp1

line1 2 ------ 5 cp2

line1 1 ------ 2 cp2

The reference doc for the hwic-4shdsl is

http://www.cisco.com/en/US/docs/routers/access/interfaces/software/feature/guide/shdslfm.html

I've tried also the original cisco cable and

swapped cp1 with cp2 , but no succes , see output :

For Oscar ,

have you tried yours and the following config also without shdsl 4-wire mode enhanced ?

Hello Patrizio,

you are configuring two HDSL each of them uses two pairs = 2+2 four wires (four wires mode means this)

so you need to use all 8 wires in a RJ-45 cable.

How to connect the 8 wires is the next step

may be you need to start from the specifications for RJ-45

for example

http://www.zytrax.com/tech/layer_1/cables/tech_lan.htm#100s

Hope to help

Giuseppe

Hi Giuseppe and Patrizio

First of all, thank you in advance for your help.

I have checked the pin-out cable and it is correct. For Patrizio; I have tried mine to configure without shdsl 4-wire but this wasn't working.

It is curious but if I connect the ISP routers those work fine, so the ISP line is OK too. I can't get access to those routers for checking the configuration. The ISP routers are both two Telindus 1421.

Hi Giuseppe,

i'm configuring one HDSL 4-wire 4mb with one group , two pair that use 2 wire = 4 wire so I need to use only 4 wires of a RJ-45 cable.

Regarding the schematic it didnt come out right but i can tell you that I'm using also Cisco cable 37-0860-01, the pinout is exactly as Figure 5 Standard RJ-45 Connector to Two Standard RJ-11 Connectors of document :

http://www.cisco.com/en/US/docs/routers/access/interfaces/software/feature/guide/shdslfm.html , of wich i'm using only one of the two RJ11 marked Ports 0,1 on the cable .

I've been doing cable for years when nodoby knew how to do a cross-cable , i came up with a cross baseT1000 when cisco cables crossed only 4 pairs and the others where straight.

(The first cross-cable i've done where with green cap , the second version all green including the cable , this is why now near all crossed cable sold are green.)

Maybe we cannot use the HWIC-4SHDSL with 4 wire and must use the HWIC-2SHDSL ?

Thanks,

Patrizio

Hi Giuseppe and Oscar,

just to let you know Telecom Italia is the provider of the BitStream line . This morning their technician come to test the line with an Aethra AC2037 , the line its OK and he told me that the Italtel DSLAM to wich we are connected does not care if the line are swapped , in fact he tried one way or the other with the AC2037 .

Also i received a WIC-1SHDSL-V3 , hereunder are the test with the same line i'm trying to make it work with the HWIC-4SHDSL .

Hi Giuseppe and Oscar,

i've made some more test.

On the first test telco-line goes to two group slave pairs 1 and 3 wires .

If the telco-line goes to the two group master pairs 0 and 2 it does not change anything.

Its a tweak , its strange but somehow it can sync the line if both pair 0 and 2 receive the signal , but of course it needs the other two pairs to complete the 4-wire handshake.

Thanks,

Hello Patrizio,

good news you have found a cabling setup that works and you have reported here.

we can say that with 6 wires you can use only a single 4wire group (this is easy to say) but you have found how to connect with tests.

Best Regards

Giuseppe

Hello Giuseppe,

in fact what i've found it that the HWIC-4SHDSL is unable to work with 1 dsl-pair group or 4 wires , it need all the 8 wires to sync even if your line its 4 wire . For this purpose i've used the original cisco cable CAB-RJ45-2RJ11 p/n 37-0860-01 using both RJ11 and attach them to a RJ11 Doubler http://www.run-it-direct.co.uk/images/RJ11Doubler.jpg .

Of course this should be not the normal way for the HWIC to work , there is something wrong with it , in fact i've also a TAC case pending , i hope the will open an escalation for the bug because the line its flapping every 50 minute .

Please note this

Dear All,

I have the same problem with 8Mbps IMA (Telecom Italia) with a Cisco 2911 with this card: EHWIC-4SHDSL-EA.

Controller is UP but SHDSL wire-pair 0,1,2,3 is DOWN.

I've tried various cabling without success.

Can someone help me?

Thanks

Salvatore

Dear Salvatore,

did you try different IOS version ?

Sometime with Telecom Italia some version do not work , and sometime also some adsl/hdsl router do not work .
