May 1999  
Before You Begin  
The Hotwirer 5446 RTU (Remote Termination Unit) interoperates with the Hotwire 8546  
DSL Card in the DSLAM (Digital Subscriber Line Access Multiplexer) system.  
An optional POTS (Plain Old Telephone Service) splitter is available for the Hotwire  
5446 RTU. When a POTS splitter is installed, the telephone and 5446 RADSL (Rate  
Adaptive Digital Subscriber Line) RTU can function at the same time over the same pair  
of copper wires. In order to confirm the RTU installation, the POTS splitter should be  
installed first.  
To install a POTS splitter, refer to the appropriate POTS splitter document:

Wiring and Cables Needed  
The following wiring and standard connectors are used with this product:  
-
New or existing unshielded twisted-pair wiring (CAT3 or better). The CAT3 wiring  
must meet EIA/TIA-568 specifications with 24 AWG (.5 mm) or 26 AWG (.4 mm).  
-
Standard RJ11 wall jack.  
-
Standard Ethernet 8-pin, non-keyed modular plug for a PC or workstation. An  
Ethernet straight-through or crossover cable is used. Refer to Installing the Hotwire  
5446 RTU, page 8, for Ethernet cable details.  
After the RTU is installed and powered on, there are additional requirements in order to  
utilize the DSL and Ethernet connections. Refer to Hotwire 5446 RTU IP Setup,

Installing the DSL Access Wiring  
The local loop terminates at the punchdown block or NID. Wiring must be connected  
from the customer premises side of the punchdown block or the NID to an RJ11 jack.  
Typically, the punchdown block is installed in commercial locations and the NID is  
installed in residential locations.  
" Procedure  
1. Access the punchdown block or NID.  
!
WARNING:  
Do not continue unless the DSL access line from the local loop has been  
disconnected at the NID or punchdown block. Refer to Important Safety  
Instructions, page 20.  
2. Disconnect the DSL access pair from the local loop.  
A punchdown block is used without a POTS splitter in the following example.

Optional RTU Wall Placement  
The Hotwire 5446 RTU is designed for tabletop placement. The RTU can also be  
mounted on a wall. To mount an RTU, you will need:  
-
Three slotted-head #6 self-threading screws with molly bolts  
-
Drill and 3/16” drill bit for the molly bolts  
-
Screwdriver  
A template with the dimensions for the three screws is provided. See RTU Hardware  
Template on page 12.  
" Procedure  
To mount the RTU:  
1. Use a drill to install the plastic anchors (molly bolts).  
2. Use a screwdriver to install the screws. Do not install the screws flush with the wall.  
Leave enough clearance to hang the RTU housing from the screws.

From the end-user system, use the PC PING utility to ping the  
5446 RTU’s IP address.  
If no response to the ping, use the PC ARP (Address  
Resolution Protocol) utility to verify the IP address and physical  
address (MAC address) from the end-user system to the 5446  
RTU. If the problem continues, contact the NSP.

Verify that the correct straight-through or crossover cable is  
installed. Refer to Installing the Hotwire 5446 RTU, page 8.  
Check that the power cord is securely installed on both ends.  
If no LEDs are on, the power supply may be defective. Test the  
outlet to verify power. If the problem persists, contact the NSP.  
If other LEDs are on, the PWR LED may be burned out. Unplug  
the unit and reapply power; watch all the LEDs during the  
power-on self-test to verify that the PWR LED is functioning.

Hotwire 5446 RTU Next Hop Router Support  
The Hotwire 5446 RTU now includes support for next hop routers and a default  
gateway.  
The following illustration includes a router and a default gateway. The maximum of 32  
end-user systems applies to end-user systems directly connected to the 5446 RTU  
(with or without a hub) and end-user systems connected to routers. Any connections to  
a default gateway are not included in the 32 systems.

Hotwire 5446 RTU IP Setup  
The Hotwire 5446 RTU hardware installation is now complete. Additional steps are  
required by the NSP to utilize the DSL and Ethernet connections.  
Network Service Provider Example  
The ISP:  
H
H
Assigns and sets up the RTU IP address and subnet mask.  
Assigns the IP address and subnet mask for each end-user system connected to  
the 5446 RTU.  
To configure the end-user system, the following is used:  
H
H
H
IP address  
Subnet mask  
Default gateway*  
*In most cases, the 5446 RTU is the upstream default gateway for all connected  
end-user systems. The other option is to connect a router between the 5446 RTU  
and the end-user system.  
Example using TCP/IP Network Settings with Windows 95:  
Set up the network configuration. Use the network settings in the Windows environment  
to enter the default gateway, IP address, and subnet mask.  
1. To configure the end-user system, from the Control Panel window, select:  
Network Configuration TCP/IP  
2. From the TCP/IP Properties window, select Gateway and enter the 5446 RTU’s  
IP address.  
3. From the IP Address window, enter the IP Address and Subnet Mask. Select OK.  
NOTE:  
Any application supported by the NSP should now start up.  
16  
 
Increasing the Number of End-User Systems  
A single end-user system is attached to the Hotwire 5446 RTU by using an Ethernet  
crossover cable. To increase the number of end-user systems, connect all end-user  
systems to an Ethernet hub using straight-through Ethernet cable. Refer to Installing the  
Hotwire 5446 RTU, page 8.  
The initial IP address for the first end-user system remains in effect when the end-user  
system is reconnected. All new end-user systems must be configured by the NSP.  
Coordinate additional IP addresses and subnet masks with the NSP.  
The 5446 RTU can support up to 32 end-user systems using static or dynamic IP  
addressing. The number of end-user systems can be increased on the network with the  
use of subnets utilizing static addresses or connecting to a default gateway. Verify any  
planned changes with the NSP.
