About the TDM SHDSL Endpoint
TDM SHDSL O vervi ew
Hotwire® Time Division Multiplex er S ymmetric High-bit-rate Digital Subscriber Line
(TDM SHDSL) products maximize customer service areas by varying the DSL line
rate. This ensures symmetric DSL connectivity over a wide range of telephone line
distances and transmission line qualities.
Hotwire products support autorate. Units first synchronize to the highest line rate
that the 2-wire loop supports, then automatically configures the unit to the highest
multiple of 64 Kbps supported by that line rate. Thirty-one line rates are available .
At all rates, a 3 Kbps Embedded Operations Channel (EOC) is available, which
enables functions such as firmware downloads to remote units. Units can also be
configured manually to full or fractional E1 ra tes.
1
Hotwire products transport data over a 2-wire, full-duplex circuit over varying
distances based on the conditions of the loop. Using 24 AWG cable, these
TDM SHDSL products have a loop reach greater than 15,000 feet (4.6 km) at
2.048 Mbps.

Using the Asynchronous
Terminal Interface
User Interface Access
You can communicate with the Hotwire TDM SHDSL endpoint with an
asynchronous terminal interface (ATI) using one of the following methods:
Direct connection through the COM port of the endpoint or through the serial
port of the DSLAM managem ent card.
Tel net session thro ugh the Embedded Operations Channel (EOC).
NOTE:
2
Only one terminal interface session can be active at a time, and another user’s
session cannot be forced to end.
Security can limit ATI access several ways. To limit user access or set up login
IDs, refer to Chapter 5,
Communication Port Settings
Ensure that the device you connect communicates using these settings:
Data rate set to 9.6 Kbps
Character length set to 8
Parity set to None
Stop Bits set to 1

Security
Overview
5
Security on the Hotwire TDM SHDSL endpoint is implemented by limiting user
access to the ATI through option settings. You can:
Enable the Telnet Login Required option.
Enable the COM port Login Required option.
Limit access by setting a Session Access Level option of Operator for the
Telnet session.
Limit access by setting a Session Access Level option of Operator for the
COM port.
Disable Telnet access with the Telnet Session option.
See Table A-7, Communication Port Options, and Table A-8, Telnet Session
Options, in Appendix A,

5. Security
ATI Access Levels
The unit has two access levels: Administrator and Operator. The access level
determines what functions are accessible, as shown in Table 5-1, Access Levels.
Access levels can be applied to Login IDs, the COM por t, and Telnet sessions.
The effective access level is always the most restrictive:
When access is through the COM port and a login is required on the COM
port, the effectiv e access level is the more restrictive of the COM port access
level or t he login access lev el. (See Table A-7, Communication Port Options, in
Appendix A,
Configuration Options
.)
When access is through Telnet and a login is required for a Telnet session, the
effective access le vel is the more restrictive of the Telnet session access le vel
or the login access level. (See Table A-8, Telnet Session Options, in
Appendix A,
Configuration Options
.)
When an access level of Operator is applied to the COM port and Telnet
sessions, a Login ID with Administrator authority is effectively reduced to
Operator.

Resetting the Unit's COM Port or Factory Defaults
The user interface can be rendered inaccessible with a faulty configuration. Two
methods can be used to restore it:
5. Security
Reset COM Port
– Allows you to reset the configuration options related to
COM port usage. It also causes a device reset, where the TDM SHDSL
endpoint performs a Device Self-Test. No security-related configuration
options are changed.
Reload Factory Defaults
– Allows you to reload the Default Factory
Configuration, resetting all of the configuration and control settings which
causes the current configuration to be destroyed and a device reset. This
method is also useful when the user’s password(s) have been forgotten.
Procedure
To reset COM port settings:
1. At a terminal directly connected to the unit’s COM port, configure the terminal
to operate at 9.6 K bps , using a character length of 8 bits, with one stop bit,
and no parity.
2. Reset the unit, then immediately and repeatedly press Enter at a rate of at
least once per second until the System Paused screen appears.
3. Tab to the desired method, and enter

initiated, with the COM port rate returning to its configured rate.
The endpoint resets itself, going through a self-test. Connectivity is restored

Controlling SNMP Access
There are three methods for limiting SNMP access:
Disable the SNMP management option. Refer to Table A-10, General SNMP
Management Options, in Appendix A,
Assign SNMP community names and access types.
Limit SNMP access through validation of the IP address of each allowed
SNMP manager.
Assigning SNMP Community Names and Access Types
The unit can be managed by an SNMP manager suppor t ing SNMP. The
community name must be supplied by an external SNMP manager accessing an
object in the MIB.
To define S NM P com munity name s, follow this menu selection sequence:

Remote Send Line Loopback
The local unit initiates this test by sending a line loopback Up or Down command
to the remote unit for 10 seconds. When the remote unit detects the loopback Up
command, it puts itself into line loopback and lights the front panel test LED. The
remote unit remains in loopback until it receives a loopback Down command or the
remote unit’s test timeout value is exceeded. The Send Line Loopback tests both
units. External equipment can be used to verify the link.

16.8 ±0.5 dBm and the transm it power of the CPE is set to 16.5 ±0.5 dBm when in data
mode. In Symmetric mode, the tr ansmit power of the CO and CPE de vices are set to
13.5 dBm when in data mode. So, for longer reach t he transmit po wer of the CO and CPE
units are increased to help with cros stalk issues. Due to this increase i n power , t he power
levels between the CO and CPE units are asymmetric.
PSD Mask only appears when DSL Mode is set to STU-C (see Table A-6, System
