Dear Aaron,
Thank for your assistance. Actually, I have followed this instruction to configure my NAS:
http://www.cisco.com/en/US/products/hw/modules/ps2797/products_configuration_example09186a00800e0dcd.shtml However, it doesn't work for me. This is the modem log rigth after the NAS has been reloaded:
sh modem log 1/0
Modem 1/0 Events Log:
00:01:27.252 DC session request: AT-I1Z
00:01:27.252 RS232: noCTS* DSR* noDCD* noRI noRxBREAK TxBREAK*
00:01:27.252 MSMP Reset
00:01:27.252 RS232: CTS* DSR noDCD noRI noRxBREAK TxBREAK
00:01:27.252 PPP escape maps set: TX map=00000000 RX map=FFFFFFFF
00:01:27.252 DTR set high
00:01:27.252 Modem disabled
Is that normal status ? Also when I pluged RJ11 phone jack on the modem port and unplug. The modem active led is green (modem active), and when I use "show interface command" I got the following:
ras3#sh interfaces async 33
Async33 is up (spoofing), line protocol is up (spoofing)
modem(slot/port):1/0, csm_state:CSM_CONNECT_INITIATED_STATE,
bchan_num:-1 csm_status: CALL_ACTIVE
Hardware is MCOM Integrated Modem Controller
Interface is unnumbered. Using address of Ethernet0/0 (10.6.20.4)
MTU 1500 bytes, BW 9 Kbit, DLY 100000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation PPP, loopback not set
Keepalive not set
DTR is pulsed for 5 seconds on reset
LCP Closed
Closed: IPCP
Last input never, output never, output hang never
Last clearing of "show interface" counters 00:08:29
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: weighted fair
Output queue: 0/1000/64/0 (size/max total/threshold/drops)
Conversations 0/0/16 (active/max active/max total)
Reserved Conversations 0/0 (allocated/max allocated)
Available Bandwidth 6 kilobits/sec
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
Please help me to indentify the problem.
Regards,
Souphonh
