INA Module Description
The MERLIN Integrated Network Access (INA) module (board code 100R) combines the voice functions of the MERLIN 100D module with data routing and a channel service unit (CSU)/data service unit (DSU). Using a T1 interface or an ISDN Primary Rate Interface (PRI), the INA module gives the MERLIN MAGIX™ Integrated System fast access to the Internet or a remote network without having to use an external CSU.
Data to and from the Internet or remote network is carried over a T1/PRI that is shared for both voice and data services. The DSU functionality of the INA module supports static allocation of the T1/PRI bandwidth to either voice channels or data channels:
•Voice. Channels allocated by the switch for voice services are available to the MERLIN MAGIX and can be used on a
•Data. Channels allocated by the switch to the router provide a
Routing functions are handled by an additional CPU that provides 32MB of dedicated RAM and special nonvolatile (Flash) RAM. The nonvolatile RAM contains router configuration data and operating firmware called ComOS. The module includes a 10BaseT Ethernet port to connect to the customer’s network.
INA Administration
To manage the INA module, you perform administrative tasks using both MERLIN MAGIX administration and router administration. Several tools for router administration are explained later in this guide. WinSPM can be used for both MERLIN MAGIX administration and router administration through the ComOS command line interface.
On the MERLIN MAGIX
For a typical application, you do the following:
