Dsl question

[galfaro]

Hello,
I have a customer who had me run a Cat 5 cable and connect his DSL line to it. The cable run was 378 ft (Warehouse) from the
D-Mark/Telco to the office. His problem is the speed. I think he said his dsl is 165.8 kilobits per second. I mostly do telephone work and i know his speed problem has to do with the length. My question is do they make some kind of booster for the DSL, like the T1, which has an extender for long cable lengths? The other option would be to relocate his work station closer.

He would have to be right on the margin of distance from his Central Office for that 378' to make a big difference.

My guess is he meant to say 165.8 kbytes per second, which would mean a connection test of 1328 kbits/second, a perfectly decent result if he is paying for a 1.5 megabits per second link.

Cat5 cabling is rated for use to a maximum of 300ft.

As I haven't got any experience of the practicalities & pitfalls of running Cat5 to this length, I'd hesitate to say this was the cause of a significant speed drop.

I'd suggest a packet sniffer on the line (or SNMP is it's supported) to see if there's much packet loss on the cat5 line.

<marc> i wonder what will happen if i press this...[ul][li]please give feedback on what works / what doesn't[/li][li]need some help? how to get a better answer: faq581-3339[/li][/ul]

manarth,

He is using the Cat5 as phone cable.

He's throwing 48 volts DC on the thing.
It is substantially better wire than what the phone company is using regularly to go 15,000 feet or more.

bcastner - you're right, of course: the Cat5 cable is fine for much longer runs...it's the Cat5 networking standard that's limited to 300 ft cable runs.

I stand corrected
