Controlling an external modem

[Duke49]

Does anyone know if you can control an external modem beyond a router, in other words is there a way to access the modem through the router. I have a Zoom 3049 modem with a serial connection to the router which connectes to the network. I would like to have this network limited to the internet, at least to novelists.

Depending on the type of modem, some come with a web interface you can access. However, if you're looking to manage your network, the ideal place would be at the router, not the modem as the modem simply creates the connection to the internet.

a router has an UPLINK to another system running the TCP/IP protocol and
several DOWNLINKS to other systems using the same protocol. it also almost
always has NAT services, meaning Network Address Translation
(the UPLINK address is different from all of the DOWNLINK addresses).

a modem (ie Modulaor - demodulator) changes analog telephone into
digital zeros-ones for a SERIAL adaptor connection to ONE system.

Consequently, most routers do not connect to modems and this is not
a technique to share ISP connectivity. When you find a professional grade
router that does have a serial connection, it is used to configure the router
from an internal system also behind a firewall, not using a modem but rather a
straight serial port <--> serial port connection.

(NOTE) this modem is not a cable/dsl modem.. it is a 56k Modem
correct me if i am wrong
Ok .... here is the deal.


what kind of router do you have... because you do not have the typical home user router because like jobeard noted most home routers do not have these types of connections and only come with the standard rj45 connection.

I am guessing you have a more business geared router. please let me know what model. Probably the router will control the modem.

I do although disagree with jobeard that most routers do not connect to a modem. in the IT industry you would be surprised with just how many routers have modem cards that can be added to them.

routers with serial or modem connectivity are used for remote management of
the device configuration, not as an alternative data transport vehicle.

again i disagree.... the company i work for has aprox 16 fax modems connected via router that handle batch fax order processing...

 

[DelJo63]

amazing ... just goes to show how limited personal experiences can be

The Router type is a D-Link Di-824-VUP. Alright, I am getting I cannot Control it from the network but I take, that it will connect to the internet through this port.

my experience has been that a serial port connection is used for a
telnet session to the router, and that can be used to control the configuration
or reboot the device. The actual commands used during the telnet session
would be documented by the vendor.

urbandragon has experiences for inbound faxing via modems, but I fear that
an outbound modem connection would be impossible. Your system needs to
see the device as a modem and to use the AT commands to perform the init, dial, el al. A connection to a router port would mask the ability to see the modem and there therefore not be able to dial outbound connections.

I'll defer to urbandragon to assist you further
