Всем привет!
Пытаюсь настроить контроллер Е1.
пишу вот это:

controller e1 0/3/0
framing CRC4
linecode hdb3
pri-group timeslots 1-31

interface serial 0/3/0:15
encaps ppp
autodetect encapsulation ppp
isdn incoming-voice modem
isdn bchan-number-order ascending

а потом пытаюсь аналогично сконфигурить второй порт Е1

controller e1 0/3/1
framing CRC4
linecode hdb3
pri-group timeslots 1-31 - и вот тут проблема.

Циска говорит что нехватает ресурсов DSP, осталось всего 2 тайм слота.

вот sh hard на циске 2821:
