Модемы Prestige 791R нужно настроить в режиме маршрутизатора, т.к. необходимо объединить разные подсети.
Приведем пример настройки модемов Presige 791R в режиме маршрутизатора. Предположим, нам необходимо связать два компьютера с IP-адресами 192.168.1.2 и 192.168.2.2 (или подсети 192.168.1.x и 192.168.2.x)
Настройки модемов можно производить как через web-конфигуратор, так и через telnet-соединение. В данном примере рассмотрим последний вариант.

Убедитесь, что значения VPI(Virtual Path Identifier) и VCI(Virtual Circuit Identifier) совпадают на обоих модемах. Для этого, в меню 11.1 установите Edit ATM Options= Yes. Откроется меню 11.6 Remote Node ATM Layer Options
VPI/VCI в котором обратите внимание на значения VPI# и VCI#. Они должны совпадать на обоих модемах.

Menu 11.6 - Remote Node ATM Layer Options

Значения Standard Mode установленые в меню 2 также должны совпадать, в противном случае соединение не будет работать.
Существует и альтернативный способ настройки двух модемов P-791R в режиме маршрутизатора. В описанном выше способе использовалась инкапсуляция ENET ENCAP и на WAN-портах модемов была создана третья подсеть, через которую и осущестлялась маршрутизация. Но можно соединить два модема в режиме маршрутизатора без создания третей подсети. В этом случае, нужно использовать инкапсуляцию RFC1483 или PPPoA и в качестве удаленного шлюза нужно будет указать LAN IP-адрес удаленного модема. Настройка данного метода приведена ниже:

Примечание: При настройке SHDSL-модемов Prestige 782R существует один нюанс. В меню 11.6 - Remote Node ATM Layer Options значение Peak Cell Rate (PCR) должно быть равно 20000 (это значение по умолчанию).
