[cisco-nas] Cisco3640 NM-16AM analog modem configuration problem

[Souphonh]

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
