Access Bank II

Welcome to Access Bank II T1 Voice Switch & Data Multiplexer from Carrier Access Corporation.
Access Bank II connects your company’s telephony and data networks to outside public and private
network DS1 services with up to 3.072 Mbps of synchronous bandwidth capacity.
The Access Bank II combines the functions of intelligent Channel Service Units (CSUs)/Data Ser­vice Units (DSUs), digital cross-connect (DCS), and digital voice switch into one product.
The Remote Monitor provides a convenient and user-friendly software interface for configuring,
monitoring, and testing the performance of the Access Bank II. The Access Bank II Remote Monitor
software interface connects to the Access Bank II through the RS-232 Management/Data Port on the
front control panel. Once the Remote Monitor application is installed on an IBM-compatible PC, you
can connect to the RS-232 Management port through a Hayes compatible modem or through a direct
connection. The Remote Monitor application can also be used from a remote PC for dial-in/dial-out
management over a separate PSTN (Public Switched Telephone Network) analog line.

The Access Bank II Remote Monitor User’s Guide describes how to set up and configure the Access
Bank II for first-time basic operation using the MS Win dows 95/ 98/NT-based Remote Monitor appli­cation installed on a PC.
The Access Bank II is a family of intelligent T1 voice and data multiplexers, available in the
following models:

• Access Bank II

• Access Bank II SNMP

• Access Bank II SDSL

• Access Bank II SNMP SDSL

• Access Exchange (Access Exchange is not covered in this manual. For
information about using Remote Monito r with Access Exchange, see the Acce ss

Exchange Remote Monitor User’s Guide.)

0.0.1 Access Bank II

The basic model of the Access Bank II provides dual-port T1 voice and data multiplexing, and is
equipped with integrated pairs of Channel Service Units (CSUs) and Data Service Units (DSUs). It
supplies up to 3.072 Mbps of synchronous bandwidth capacity for connecting customer premises
telecommunications equipment to public and private network DS1 services. A V.35 port for internet
or router connections may be configured for up to 1.5 Mbps on one T1, while all 24 voice channels
are terminated on a second T1. A single T1 with a mixture of voice and data can also be used.

0.0.2 Access Bank II SNMP

The Access Bank II SNMP offers all of the features of the Access Bank II, with the following
additional features:

• An embedded Simple Network Management Protocol (SNMP) agent supporting
MIB-II and standard MIBS for T1 and V.35 via TCP/ IP over a 10base-T Ethern et
connection.

• A Command Line Interface (CLI ) for local or r emote management via RS-232 or
telnet connections.

Welcome

0.0.3 Access Bank II SDSL

The Access Bank II SDSL provi des T1 voice and data multiplexing, and is equip ped wi t h in te grated
Channel Service Unit (CSU) and Data Service Unit (DSU). It supplie s up to 1.536 Mbps of
synchronous bandwidth capacity for connecting customer premises telecommunications equipment
to public and private network DS1 services. In the place of the second T1, the Access Bank II SDSL
provides an SDSL port. Some of the benefits of using SDSL are as follows:

• Because SDSL connect ions are di gital from end t o end, the dat a trans fer rates are
optimized.

• SDSL connections use standard copper phone wires for connections to routers
and other data applications.

0.0.4 Access Bank II SNMP SDSL

The Access Bank II SNMP SDSL offers all of the features of the Access Bank II, with the following
additional features:

• An embedded Simple Net w ork Mana gemen t Prot oc ol (SNMP) agent supporting

connection.

• A Command Line Interface (CLI ) for local or r emote management via RS-232 or
telnet connections.

• Because SDSL connect ions are di gital from end t o end, t he data transfe r rates are
optimized.

• SDSL connections use standard copper phone wires.

General Rules and Tips for Using the Remote Monitor

1.8 General Rules and Tips for Using the Remote Monitor

The Remote Monitor is designed for easy setup, configuration, monitoring, and management of the
Access Bank II. Following certain rules and tips will ensure more reliable r esults. The follo wing
sections describe these rules and tips.

• Be sure you have the correct product selected before you begin making screen changes,
or you will have to begin th e change s again . The Remote Moni tor, when started, defaults
to the Access Bank II product.

1.8.1 Reading and Sending Screens

Send all scre ens to unit. Click on this icon to
send all data from Remote Monitor to your
Access Bank II unit.

Read all screens from unit. Click on this icon to
read all data on your Access Bank II and display
it in Remote Monitor.

Send all flagged screens to unit. Click on this
icon to send all of the screens you’ve flagged in
Remote Monitor to your Access Bank II.

Clear all flags. Cl ick on this icon to cle ar all flags
in Remote Monitor without sending the flagged
screens.

Send current screen to unit. Click on this icon to
send the data on the current Remote Monitor
screen to your Access Bank II.

Read current screen from unit. Click on this icon
to read the da ta for the current Remote Monitor
screen from your Access Bank II.

• Reading screens means loading information displayed on the current configurable
screens, and some non-configurable information, from the Access Bank II into the
Remote Monitor. Sending screens means downloading the informatio n dis pla yed on the
current or flagged configurable screens from Remote Monitor into the Access Bank II.

• When reading screens from t he Acces s Bank I I or se nding s creens to th e Access Bank II ,
canceling the transf er can re sult in a partial trans fer and a corrupt ed conf igurat ion. If this
occurs, redo the correct read or send operation to clear up the problem.

• When changing screens, it is often best to change all the screens you want to change
before sending screens to the Access Bank II. Some screens are interactive with others
(specifically the Static Connection, Channel/Signal Type, and V.35 Data screens in the
Connections group), and must be read or sent together.

1-13

• You can read and send most screens individually, all together, or send just the flagged
screens. Sending all screens takes longer, therefore it is more efficient to send only
changed screens. One way to do this is to fl ag each scr een you chan ge, then use t he Send
All Flagged Screens to Unit icon or Connection menu item. Remember to unflag all
screens after they are sent.

1-14

General Rules and Tips for Using the Remote Monitor

1.8.2 Screen Flagging

• The screen-flagging feature is a tool to help you remember which screens you have
changed, that you have not sent them to the Access Bank II, and to allow you to more
efficiently send changes to the Access Bank II. It is not an automatic-flagging feature;
you must manually flag and unflag screens. Screens are flagged or unflagged by right­clicking on the screen tab.

1.8.3 Changing to a New Product

• When you click the New Product item on the File menu, then click on a product name,
the default configuration is loaded. You can also do the same thing by selecting a differ­ent product name from the Current Product dropdown menu on the to olbar. Any changes
not saved will be lost.

• If you check the “Please don’t ask me about this again” box on the warning screen, the
system will always prompt you to save the configuration file for the previous product.
Note that this will cause this particular question to always be answered Yes.

1.8.4 Saving Configurations

• Save Configuration and Save Configuration As save the current configuration to a file
(database) on the Remote Monitor PC’s hard drive. If you made changes to screens of a
configuration you loaded previously, Save Configuration will overwrite the original con­figuration file.

• If you have previously checked Please Don’t Ask Me About This Again on the Confirm

Configuration File Save on Open/New confirmation screen that appears when you loa d a
configuration, soft ware as sumes you wa nt to s ave and a sks you f or a f ile na me. If you do
not want to save, simply Cancel

•The Compact Configurat ion File opt ion on the File pul l-down me nu compre sses t he con -
figuration file to about one fifth its original size.

• If you are working in the field, it can be useful to keep several configuration files on a
floppy disk.

1-15

1.8.5 Loading Configurations

Any configurations that have been saved from the Remote Monitor can be reloaded. When the
Remote Monitor is first loaded, there are no other configurations that can be loaded. The default
configuration (for Access Bank II) must be saved, or modified and saved before anything appears in
the list of load able files. Load ing a configuration into the Re mote Monitor from an existing file can
be initiated two ways.

• Use the Load Configuration From File icon:

1. Click on the Load Configuration From File icon.

• Use the File pull-down menu:

1. Click on the word File at the top of the screen.

2. Click on Open Configuration in the pull-down menu.

A window appears, asking you if you want to save the current configuration to a file. A Yes
answer allows you to assign a file name and sa ve the configuration, then selec t the file name
you want to load. A No answer allows you to select the file name you want to load without
saving the current configuration.

3. Select the file you want to load and click on Open.

1.8.6 Miscellaneous

•The S tatic Conne ctions scr een must be con figured bef ore you can configu re the Channel
Type screen because the Channel Type screen only affects drop and insert channels,

which must be mapped on the Static Connections screen.

• You can enter information (typing or menu selections) in any screen field that is white.
You cannot enter information in gray fields.

• When requesting event s o n t he Ev ent Log s cr een, be aware that reques ti ng a ll eve nt s ca n
take several minutes, and during that time you cannot scroll past event 15, so consider
requesting six even ts at a time. Also, er asing the ev ent l og (cl ears all e vents) peri odicall y
is helpful.

System Setup Screens

Chapter 2

System Setup

2.1 System Setup Screens

The System Setup screens guide you through the naming of the system components, problem
reporting, remote management, system clock, and SNMP setup. The first thing you must set up is
Remote Management so you can connect to the Access Bank II, and the Send and Read operations
between the Remote Monitor and the Access Bank II will work.

Note: After making changes t o the conf iguratio n on any scr een, you must send th e

changes to the Access Bank II before the changes will take effect. To do this, click
on Send Current Screen to Unit in t he Connect ions pull- down menu , or clic k on t he
Send icon at the top of the scre en. If you make changes to many scre ens, you can use
the Send All Configurable Screens to Unit ite m on the Connections pull -down menu.

2.1.1 Flagging Changed Screens

The Remote Monitor provides a method for flagging screens you change as you set up the Access
Bank II. It is a user-initiated feature. That is, you must actively flag and unflag the screens yourself.
This feature makes it easier for you to remember to send all the changed screens to the Access Bank
II.

To flag a screen you have changed, simply right-click on the screen tab when that screen is active,
and a flag symbol appears on the tab. To unflag a screen, right-click it again, or click the Clear all
Send Flags icon.

Alternately, you can use the Clear All Send Flags and Send All Flagged Screens options on the
Connections menu.

The screen flags are not automatically cleared when you send screens to the Access Bank II.

2-1

2.1.2 Names Screen

The Names screen allows you to assign names to the system and the T1, Data, and FX voice ports.
Simply type the names you want to assign in the respective fields. When you are finished with all
setup entries, it is a good idea to save the configuration. If you want to save the configuration in a
new configuration file, use the Save Configuration As selection.

Ensure that the Current Product window displays the appropriate Access Bank II product. If another
product is displayed, see Selecting the Current Product in Chapter 1.

2-2

System Setup Screens

2.1.3 Problem Reporting Screen

To set up the problem reporting screen, left click in the appropriate box for each alarm listed,
selecting the type of reporting you want each alarm to use, logging or dialout. Enter the pager alarm
or printer alarm telephone number to which you want the dialout alarms to be sent, and enter the
message you want to be conveyed. This dialout feature will only operate if a modem is connected to
the Access Bank II.

2-3

2.1.4 The System Clock Screen

Use the System Clock screen to synchronize the Access Bank II clock with the management PC
clock, or manually set the Access Bank II clock to any time you want. To synchronize the clocks,
simply click on the Local Synchronize button, and send the screen to the Access Bank II. To set the
Access Bank II clock manually, click on the + and - buttons in the Access Bank II Clock/Calendar
window until the time is correct. Then send the screen to the Access Bank II.

2.1.5.1 Configuring Network Parameters

Several basic settings are required before using the SNMP/Telnet facilities provided by Access Bank II. The
basic settings to be configured by the user are:

IP Address

The Internet address identifies the Access Bank II on a TCP/IP based network. This field is required – each
Access Bank II on the network must have a unique IP address. If your network is part of a larger wide area net­work, your site has been assigned a range of addresses for your network.

Subnet Mask

Networks that require further partitioning use subnet masks to perform subnet routing. These values indicate
which part of your IP address is a network address and which part is a node address.

Default Gateway

This is the IP address of a default gateway on your logical network. A TCP/IP gateway (router) allows you to
communicate outside your local network (subnet) by forwarding information to another network. The gateway
must be on your logical netwo rk; t he net work portion of the address should be the same as the network portion
of your IP address.

2.1.5.2 Configuring SNMP Traps

The Access Bank II SNMP agent supports the Stand ard SNMPv2 defin ed traps. In the future enterp rise specific
traps are to be added. Interpretations of the trap values are:

2-5

coldStart Trap and warmStart Trap

These traps are combined in the Access Bank II:

A coldStart(0) trap signifies that the sending protocol entity is reinitializing itself such that the agent’s configu­ration or the protocol entity implementation may be altered. This is typically a power reset.

A warmStart(1) trap signifies that the sending protocol entity is reinitializing its el f such that neither the agent
configuration nor the protocol entity impl ementatio n is altered. This is typically a software reset.

linkDown Trap

A linkDown(2) trap signifies that the sending pro toco l entity recognizes a failure in one of the communication
links represented in the agent’s configuration. The Trap-PDU of type linkDown contains as the first element of
its variable-bindings, the name and value of the ifIndex instance for the affected interface.

linkUp Trap

A linkUp(3) trap signifies that the sending protocol entity recog ni zes that one of the communication links rep­resented in the agent’s configuration has come up. The Trap- PDU of type linkUp contains as the first element of
its variable-bindings, the name and value of the ifIndex instance for the affected interface.

authenticationFailure Trap

An authenticationFailure(4) trap signifies that the sending protocol entity is the addressee of a protocol message
that is not properly authenticated. While implementations of the SNMP must be capable of generating this trap,
they must also be capable of suppressing th e emissio n of such trap s via an implementation-specific mechanism.

enterpriseSpecific Trap

A enterpriseSpecific(6) trap signifies that the sending protocol entity recognizes that some enterprise-specific
event has occurred. The specific-trap field identifies the particular trap, which occurred (to be implemented in
the future).

Warning: To use the Trap Facilities, you must configure at least one of the three available NMS

addresses to receive the trap messages.

2-6

System Setup Screens

2.1.5.3 Configuring System Group Information

The values that can be configured are:

System Name

The system Name is a string of 1-123 characters that is the administrative assigned name for this managed
node.

Location

This is a string of 1-123 characters that describes the physical location of this node.

Contact

This is a string of 1-123 characters that identifies the contact person for this managed node, together with infor­mation on how to contact this person.

2.1.5.4 Security

The SNMP agent supported by the Access Bank II includes authentication. An authentication assures a recipi­ent that a message is from the source it claims to be from.

Get Community

Every SNMP message from a management station to an agent includes a community string. This name func­tions as a password and the message is assumed to be authentic if the sender knows the password.

Set Community

In order to allow a Network Manager for SNMP to alter your local parameters. You must add a string here. By
default, this read/write access is disabled. Adding a string enables this capability, and the network manager
must know the keyword to perform sets.

Trap Community

When an extraordinary event occurs at the agent, the managed node usually sends a single, simple trap message
to the Network Manager. Traps are asynchronous notifications that are predefined in the MIB and must be
known to both the agent and the Network Manager.

T1 Setup

3.1 T1 Setup

The T1 Setup screen allows y ou to confi gure the T1 sp ans for your instal lation. T1 Setup fields are used

to set up the T1 network interfaces to match the characteristics of the attached T1 data streams, such as line
code, framing format, and enabling detection of inband CSU loop codes

3-1

3.1.1 System Clock Source

The T1 Setup screen also allows you to set the system clock sour ce. The clock source is used for ti m­ing the transmit side of all the T1s and for the Tx and Rx clock signals on serial data ports. We rec­ommend setting the primary and secondary clocks to different sources.

3.1.2 T1 Hardware Setup

You can configure the T1 network interface to match characteristics of attached T1 data streams.

To configure the T1 network interface:

3.2 T1 Definitions

T1 Hardware Setup fields are used to set up the T1 network interfaces to match the characteristics of the
attached T1 data streams, such as line code, framing format, and enabling detection of inband CSU loop co des.
The fields are defined below.

3.2.1 Framing: D4 or ESF

Selecting D4 sets the basic frame structure to the 12 frame D4 Superframe format. If ESF is selected, the basic
frame structure of the attached T1 span line should be the 24 frame ESF Extended Superframe format, which
includes a 4 Kbps Facility Data Link (FDL) channel for supervisory and performance monitoring.

3.2.2 Line Coding: AMI or B8ZS

Set the line coding either to Alternate Mark Inversion (AMI) (Default) or Binary 8 Zero Substitution (B8ZS).
B8ZS allows for 64Kbps clear channel operation, required for most data applications.

3.2.3 CSU On/Off: Ignore or Detect

Causes the ACCESS Bank II to either ignore or respond to the inband D4/ESF CSU loop up (…00001…) or
loop down (…001…) codes. Detect is the d e fau lt setting.

3.2.4 PRM Type: AT&T 54016 or ANSI T1.403

Detect AT&T 54016 or ANSI T1.403 ESF out-of-band loop codes with the exact loop code type detected as
specified above, and FDL Messaging.

3.2.5 Self Test: OFF or ON

Place T1 Span 1 or Span 2 in an internal loopback configuration and perform system self test, and provide to
FSX channels either ringback or a 1000 Hz test tone.

3-3

3.2.6 Line Build Out (LBO):

CSU 0 db/DSX (0’-133’), CSU -7.5 dB, CSU -15 dB, CSU -22 dB, DSX (133’-266’), DXS
(266’-399’), DSX (399’ - 533’), DSX (533’-655 ’)

Selects the signal level to be transmitted from the Access Bank II to the T1 line(s). The

default is 0 dB/DSX (0’-133’), which is the normal signal level required by most public car­riers. It is important to remember that this setting can only be changed in the Remote mode.
A T1 signal level too high for the engineere d fac ilit y can resul t in B ipolar Violations (BPV).
Too low a level can result in signal loss (LOS). Verify in advance the proper signal level
required by your service provider.

V.35 Data Port Setup

Chapter 4

Data Port Setup

4.1 V.35 Data Port Setup

The Access Bank II cont ro l panel contains a V.35 DCE port for connecting t o s ync hronous DTE data
sources such as routers and FRADs from 56 Kbps to 1,536 Mbps in N = 1 to 24 Nx56/Nx64 Kbps
steps. There are no physical DIP switches for configuring this high-speed serial interface. The V.35
screen allows you to set up and operate the Access Bank II V.35 DCE interface.

4.1.1 Setting the Speed Option

The port speed can be set for either Nx56 or Nx64. Set this option for the available bandwidth.

4.1.2 Setting the Receive Timing Option

The receive t iming can be set for either Intern al or External. In ternal is the se tting for normal op era­tion. External can be used whe n requir ed by d ata equip ment connec ted to t he Access Bank II. I nternal
means the V.35 clock is recovere d from the Access Bank II timing, whi ch is usually der ived from one
of the T1’s. External means clocking is recovered from the connected DTE device (via pins U and
W).

4.1.3 Setting the Data Option

The data option can be set for Normal or I nverted. Se t as requi red by data e quipment connect ed to the
Access Bank II. Inverted has the same effect as reversing the A (+) and B (-) pins of both Transmit
Data and Receive Data.

4.1.4 Setting the DSU Option

DSU can be either Enabled or Disabled. Disable when you don’t want a V.54 DSU code to cause a
loopback on the data port.

4.1.5 Setting the Clock Option

The clock can be set for No In ver si on, Receive Clock (RxCLK) Inversion, Transmit Clock (TxCLK)
Inversion, or RxCLK and TxCLK Inversi on. No Inve rsion is the correct s etting f or normal operat ion.
Set as required by data equipment connected to the Access Bank II.Inverted has the same effect as
reversing the A (+) and B (-) pins of the affected clock signal.

4-1

4.1.6 Setting the CTS Control Option

CTS Control can be set to force CTS high, force CTS low, follow RTS, or follow CD. Force CTS
high is the correct setting for normal operation. Set as required by data equipment connected to the
Access Bank II.

7-4

The Event Log Screen

Performance information is monitored for Network Loopback Seconds, Loss of Carrier, Alarm Indication Sig­nal, Loss of Frame Count, Yellow Alarm Seconds, Unavailable Seconds, Severely Errored Seconds, Errored
Seconds, and B i polar Violations.

7.1.4 Definitions

Network Loopback Seconds - When a Network Loopback is activated, either via the T1 Hardware
setup screen or the Maint en anc e scr een, the Access Bank II software sta rt s to incr emen t se cond s tha t
the loopback is active.

Loss of Received T1 Signal - Also called Loss of Carrier

Alarm Indication Signal (AIS) Defect - For T1 links, the ’a ll ones’ condition is detected upon

observing an unframed signal with a ones density of at least 99.9% present for a time between 3 and
75 ms. The AIS is terminated upon observing a signal not meeting the one’s density or the unframed
signal criteria for a period equal to or greater than the same time period that caused the system to
enter the AIS state.

Loss of Frame Count - For T1 links, the Loss Of Frame failure is declared when an OOF or LOS
defect has persisted for between 2 and 10 seconds. The Loss Of Frame failure is cleared when there
have been no OOF or LOS defe cts duri ng a period T where 0 <= T <= 20. Many systems will perform
"hit integration" within the period T before declaring or clearing the failure e.g., see TR62411.

Yellow Alarm Seconds - The Far End Alarm failure is also known a s "Yellow Alarm". For D4 links,
the Far End Alarm fai lur e is de cla re d whe n bi t 6 of al l c han nel s has been zero for at le ast 3 35 ms and
is cleared when bit 6 of at least one channel is non-zero for a period that is usually less than one sec­ond and always less than 5 seconds. The Far End Alarm failure is not declared for D4 links when a
Loss of Signal is detected.

For ESF links, the Far End Alarm failure is declared if the Yellow Alarm signal pattern occurs in at
least seven out of ten contiguous 16-bit pattern intervals and is cleared if the Yellow Alarm signal
pattern does not occur in ten contiguous 16-bit signal pattern intervals.

Unavailable Seconds (UAS) - Unavailable seconds are calculated by counting the number of sec­onds that the interface is unavaila ble. The DS1 interfa ce is said to be unavailable fr om the onset of 10
contiguous Severely Errored Seconds (SES), or the onset of the condition leading to a failure (see
Failure States). If the condition leading to the failure was immediately preceded by one or more con­tiguous SESs, then the DS1 interface unavailability starts from the onset of these SESs. Once
unavailable, and if no failure is present, the DS1 interface becomes available at the onset of 10 con­tiguous seconds with no SESs. Once unavailable, and if a failure is present, the DS1 interface
becomes available at the onset of 10 contiguous seconds with no SESs, if the failure clearing time is
less than or equal to 10 seconds. If the failure clearing time is more than 10 seconds, the DS1 inter­face becomes available at the onset of 10 contiguous seconds with no SESs, or the onset period lead­ing to the successful clea ring c onditi on, whicheve r occur s lat er. With respect to t he DS1 error counts ,
all counters are incremented while the DS1 interface is deemed available. While the interface is
deemed unavailable, the only count that is incremented is UASs.

7-5

Severely Errored Seconds ­Errored Seconds (LES) - A Li ne Er ror ed Second, according to T1M1.3 , i s a second in which o ne or

more Line Code Violation error events were detected.

Bipolar Violation (BPV) Error Event -A BPV error event for an AMI-coded signal is the occur­rence of a pulse of the same polarity as the previous pulse. A BPV error event for a B8ZS- or HDB3­coded signal is the occurrence of a pulse of the same polarity as the previous pulse without being a
part of the zero substitution code.

8.2 Analog Ports

The 24 available analog ports are associated with the voice channels and plug-in analog cards of the
Access Bank II. The analog port status is activated upon entering the screen and displays the signal­ing bits associated with the card type and its signaling type configuration. The Analog Port Status
screen allows the user to monitor the signaling bits in real time as it auto-reads the current status from
the Access Bank II at specified intervals (you must be connected to an Access Bank II).

For each analog card the following data is monitored and described in the table below.

Name Values Comments
Quiet Channel 0=Off, 1=On Idle/Active State
Ringback 0=Off, 1=On

Transmit "A" 0, 1 Signaling to network
Transmit "B" 0, 1 Signaling to network
Receive "A" 0, 1 Signaling from network
Receive "B" 0, 1 Signaling from network
Trunk Processing 0=Off, 1=On

Self-test 0=Off, 1=On

The contents and meaning of the signaling bits depends on the type of signaling used by the circuit
provided over the channel. The Robbed-Bit signaling states for the following types of circuit signal­ing are provided in the tables below for the D4 (SF) and ESF framing formats. The types are:

• Loop-Start signaling

• Ground-Start signaling

8.3 LEDs

The Access Bank II allows the user, from a remote site, to monitor the signaling state of the Signal
Leads for the various dat a por ts tha t a re pr ovi de d. If the signal on the Lead is active high , it is shown
in the color blue; otherwise it is not lit. This is useful for diagnosis of the data ports. In addition, the
various LEDs on the fro n t pane l are also displayed. Thi s screen auto-updates a t a default rate of once
every 5 seconds, which you can change, or turn off, with the slide control.

The Battery State LED indicates the status of the Access Bank II internal battery. When the LED is
on, or Green, the battery is OK, or present. If the battery is dead, or not present, the LED is off, or
gray.
