Displaying DS0 Channel Assignments
Use the Cross Connect Assignments screen to view which DS0 channels are
currently assigned to the data port. Below each DS0 channel you will see either
“Available” or “P”. DS0s with a “P” designation are assigned to the data port.
DS0s marked “Available” are unused (unassigned).
Cross Connect Assignments may also be displayed by accessing the Cross
Connect Status screen under the Status branch of the Main Menu.
Using the Block or ACAMI Assignment Method
By using the block or ACAMI (Alternate Channel Alternate Mark Inversion)
assignment method, you can assign a data port to a block of contiguous DS0
channels on the network interface.
The block assignment method allows a block of contiguous channels to be
assigned by specifying the number of DS0’s to allocate and an initial DS0
channel (the first DS0 channel in a block of DS0 channels). The number of
channels assigned is determined by the port rate. These channels are
automatically assigned to the destination network interface when the initial DS0
channel is selected.
Configuring the DSU/CSU
The ACAMI assignment method also allows a block of contiguous channels to be
assigned. However, with ACAMI, the number of channels assigned is twice the
number needed for the port rate. This is because with ACAMI, every alternate
n
DS0 channel (starting with the
port, but instead always transmits and receives all ones.

Using the Individual Channel Assignment Method
This channel method allows you to select the individual DS0 channels to allocate
to the data port. The data port rate is automatically determined based on the
number of channels selected. The DS0s do not need to be contiguous.
Procedure
To assign the data port by the individual channel method:
1. Access the Cross Connect Assignments screen by following this menu
selection sequence:
Main Menu→Configuration→Load Configuration From
Cross Connect
2. Use the Assign By field to specify the assignment method (Channel).
3. Specify the port assignments for the individual DS0 channels. The DS0
channels do not need to be contiguous.
4. The port rate increases as the port is assigned to each additional DS0
channel. For example, if two DS0 channels (at 64 kbps each) are assigned to
the data port, a port rate of 128 kbps is required.

Resetting the DSU/CSU’s COM Port or Factory Defaults
Misconfiguring the access unit could render the user interface inaccessible,
leaving it in a state where a session cannot be started via the COM port or a
Telnet session. If this occurs, access unit connectivity can be restored via a
directly connected terminal.
Two methods can be used to restore access to the user interface:
HReset COM Port – Allows you to reset the configuration options related to
COM port usage. This also causes a device reset, where the access unit
performs a Device Self-Test. No security-related configuration options are
changed.
HReload 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 the async terminal that is directly connected to the access unit, configure
the terminal to operate at 9.6 kbps, using character length of 8 bits, with one
stop-bit, and no parity.
2. Reset the access unit, then immediately and repeatedly press Enter at a rate
of about 1 press per second until the System Paused screen appears.

ATI Access
Access to the ATI is available through either the Terminal port or a Telnet session.
Access to the ATI through the Terminal port can be limited. Refer to Table A-6,
Terminal PortOptions, to:
Enable Login Required.
Assign a Port Access Level of 1, 2, or 3.
The ATI can be accessed remotely through a Telnet Session via either the
Ethernet port or the FDL. The DSU/CSU provides several methods for limiting
access to the ATI through a Telnet session.
Refer to Table A-7, Telnet Session Options, to:
— Enable Login Required.
— Assign a Telnet Session Access Level of 1, 2, or 3.
— Disable Telnet access completely.
To prevent the 10BaseT port and FDL from supporting a Telnet session:
— Set the Ethernet Port Use option to Disable. Refer toTable A-5, Ethernet
PortOptions.

Effective Access Level
Security
The ATI effective access level (Table 4-1) is the more restrictive of:
Port/Session access level, or
The Access level associated with the Login ID.
For example, if a login ID is created with an Access Level 1 and the Terminal Port
is set for a Port Access Level of 2, the effective access level to the ATI is 2.
When user access to the ATI is attempted through the Terminal port or a Telnet
session, the ATI response is based on the Login Required option and the
availability of the ATI. Table 4-2 describes how the system responds to various
ATI access conditions.

IP Addressing Examples
Management of IP addressing is based on individual IP addresses assigned to
each interface. The IP interfaces for the unit are:
Ethernet port – See Table A-5, Ethernet Port Options.
FDL – See Table A-2, Network Interface Options.
NOTE:
Do not assign IP addresses without the assistance of the network manager or
individuals responsible for determining the IP addressing scheme for your
organization.
The following examples apply to IP (SNMP) management traffic only. The subnet
mask shown for these examples is 255.255.255.000.
Local Addressing Only (No FDL)
In the following example, the DSU/CSUs do not use the FDL for management
communications. This can be the result of using Fractional T1 service or Frame
Relay Service. In this example both DSU/CSUs:
Only receive management data through the 10BaseT port connection.
Do not route the data between themselves. Routers route the management
data for the connected DSU/CSUs using the user data path between the
routers.
The following illustration shows each DSU/CSU with its own IP address on the
LAN subnet.

DSU/CSU A is connected to DSU/CSU B through the FDL.
DSU/CSU B is addressed through the FDL as if it existed on LAN A.
DSU/CSU A forwards all data to DSU/CSU B using Proxy ARP.
A proprietary RIP is used to learn the IP addresses of the remote FDL
interfaces. It can take up to 5 minutes for the RIP protocol to exchange
addresses once the FDL is active.

Network Performance Statistics
Network performance statistics allow you to monitor the current status of the
network operations. Performance statistics can assist you in determining the
duration of specific conditions and provide a historical context for problem
detection and analysis.
When the network interface is configured for ESF framing, network performance
is continuously monitored and maintained in two sets of aggregate registers:
These status registers collect performance data for the previous 24-hour period.
Performance data is updated in 15-minute intervals. After 15 minutes, the current
interval is rolled over into a set of accumulator registers that represent the
previous 96 15-minute intervals for the register. An interval total of how many of
the 96 registers contain valid data is also kept, as well as a 24-hour total for each
accumulator register.
To view the Network Performance Statistics, follow this menu selection sequence:

The User counter for ESF Error Events can only be reset by selecting the
ClrStats option or by resetting the device.
Network performance statistics are kept for each 15-minute interval over the past
24-hour period. There are six types of statistics recorded:
Errored Seconds (ES) – The number of errored seconds for the current
interval. An errored second is any second with one or more ESF error events.
The maximum is 900 seconds.
Unavailable Seconds (UAS) – The number of unavailable seconds for the

Bursty Errored Seconds (BES) –The number of bursty errored seconds for
the current interval. A bursty errored second is any second with more than
one, but less than 320, CRC errors. The maximum is 900 seconds.
Controlled Slip Seconds (CSS) – The number of controlled slip seconds for
the current interval.
Loss of Frame Count (LOFC) – The loss of frame count for the current
interval. This is a count of the number of times that an LOF is declared. The
maximum count is 255.
A Telco set and a user set are kept for each of the above statistics. The user set
is a copy of the Telco set, but the user set can be cleared.
In addition to the statistics kept for the network interface, the system maintains a
Status register for each interval (far-right column). The Status register shows
whether or not the following events have occurred at least once within the
15-minute interval:
Y – Yellow Alarm
L – Loss of Signal
E – Excessive Error Rate
F – Frame Synchronization Bit Error
V – Line Code Violation
