NM-6DM Overview
The internal digital modem network module is available with 6, 12, 18, 24, and 30 pre-installed modem configurations that are field-upgradeable to 30 modems by adding additional modem modules. This provides maximum dial solution expansion for a growing remote user base.
Support for the new V.90 modem technology allows users to achieve maximum data transfer rates, while still allowing support for V.34 technologies. The modems are software upgradable and can support future standards as they become available. High-speed capability ensures rapid download of Web pages and files.

Frequently Asked Questions (FAQs)
What primary function does the Cisco NM-6DM module serve in a branch router? +
The NM-6DM is a dedicated network module designed for Cisco modular routers to provide integrated dial-up access capabilities. By housing six digital modems, it allows remote users or legacy out-of-band management systems to connect to the router via standard telephone lines, facilitating reliable remote access and dial-in connectivity in environments where broadband or Ethernet connections are not feasible.
Does the NM-6DM module support full 56 Kbit/s data rates? +
Yes, each of the six integrated digital modems on the NM-6DM supports V.90 and V.92 standards, enabling downstream data rates up to 56 Kbit/s. It is optimized for high-quality analog line terminations, ensuring efficient data transmission for faxing, remote management, or low-bandwidth telemetry applications across the public switched telephone network.
Which Cisco router platforms are compatible with the NM-6DM modem module? +
This module is compatible with a wide range of Cisco modular routers that feature standard network module (NM) slots. It is commonly deployed in classic Cisco 2600, 3600, and 3700 series routers. Always verify your specific chassis model and available slot type to ensure physical compatibility and adequate power headroom before installation.
How are the individual modems on the NM-6DM managed within the Cisco IOS environment? +
Once installed, the NM-6DM is managed directly through the Cisco IOS command-line interface. Each modem appears as an individual asynchronous interface, allowing administrators to configure specific dial-in parameters, security authentication, and line protocols. You can group these lines under a rotary group to streamline incoming call distribution across the six available ports.
Can the NM-6DM be used for out-of-band management in a data center? +
Absolutely. The NM-6DM is a frequent choice for out-of-band management scenarios. If your primary network link goes down, the modems provide an alternative pathway for administrators to dial into the router console port via a telephone line. This provides a critical fail-safe, ensuring you maintain administrative control over your network hardware even during major outages.
What type of cabling is required to connect the NM-6DM to the telephone network? +
The module typically utilizes RJ-11 interfaces to connect directly to standard analog telephone lines. Depending on your local infrastructure, you may require patch cables or specific telco cross-connects to interface the module with your provider’s analog circuit terminations. It is designed for straightforward integration into existing analog voice telecommunications cabling setups.
Is the NM-6DM suitable for high-density dial-out applications? +
While the NM-6DM can support both dial-in and dial-out operations, it is specifically optimized for applications requiring moderate density. With six integrated modems, it is ideal for medium-sized branches requiring concurrent dial access. For massive scale requirements, you might consider distributing these modules across multiple router slots to increase your total modem density and resource availability.
How does the NM-6DM handle power consumption within the router chassis? +
The NM-6DM module draws its power directly from the host router's backplane. Because it manages six active modem controllers simultaneously, it is important to ensure your router power supply has sufficient capacity. In most standard installations, the module operates within the defined power budget of the supported Cisco router platforms, maintaining consistent stability during peak traffic periods.
