[asterisk-users] Timing cable usage necessity

[Захаров Антон]

Здравствуйте.

Спасибо за ответ. Меня какраз интересуют проблемы, которые решает этот 
кабель. Достать его теоретически мы сможем. Другой вопрос, в чем же его 
уникальность? И почему, например, нельзя использовать floppy кабель?
Когда я поставил floppy кабель вместо "официального" и модулю указал 
опцию "timingcable=1", у меня либо вообще система падать стала (так, что 
коннект по ssh терялся), либо в asterisk я получал сообщение Bad HDLC и 
поток не поднимался.

Hello.

Thank you for your reply. I'm interested in problems that solves this 
cable. We can get it theoretically. Another question, what is its 
uniqueness? And why, for example, we can not use the floppy cable?

When I put the floppy cable instead of an "official" and set the option 
module "timingcable = 1", I either do a system has to fall (so that the 
connection was lost over ssh) or I get the message Bad HDLC in asterisk 
and the E1 flow was not raised.
