INA Module 1
This chapter introduces the MERLIN Integrated Network Access (INA) module and
provides an overview of its installation and configuration. The following topics are
discussed:

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 channel-by-channel basis to support
incoming or outgoing calls.
• Data. Channels allocated by the switch to the router provide a high-speed data pipe
for dedicated Internet or remote network access.
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:
