1.1 About This Chapter
This chapter provides a general introduction to Carrier Access Corporation’s Access Bank II SNMP
and includes summaries of its:
• Physical Characteristics
• Features, Functions, and Optional Enhancements
• Digital and Analog Interfaces and Connectors
• Local and Remote Network Management
1.2 General System Overview
The Access Bank II SNMP is an intelligent dual-port T1 voice and data multiplexer equipped with
integrated pairs of Channel Service Units (CSUs) and Data Service Units (DSUs). It supplies up to
9/24/01 1-1
3.072 Mbps of synchronous bandwidth capacity for connecting customer premises telecommunications equipment to public and private network DS1 services. An Internet or router V.35 port may be
configured for up to 1.5 Mbps on one T1, while all 24 voice channels are terminated on a second T1.
1.3 Features, Functions, and Options
The Access Bank II SNMP combines the functions of an intelligent CSU/DSU, digital access &
cross-connect switch (DACS), and channel bank in a single product that includes the following standard features, functions, and options.
1.3.1 Standard Features
• Dual T1 ports with integrated diagnostic ESF CSUs
• 3.08Mbps total available bandwidth
• V.35 DCE data port (to 1.536Mbps)
• Drop and Insert (D&I)
• DS0 Digital Cross-Connect System (DCS)
• Command line interface (CLI) for local or remote mangement.
• RS-232 Command Line Interface and optional Remote Monitor program.
• Embedded SNMP agent supporting MIB-II and standard MIBS for T1 and V.35 via a
TCP/IP and 10base-T Ethernet connection
• 115 Vac to -48 Vdc Power Converter Cube
• Standard 25-pair female telephone cable connector
1.3.2 Software Programmable Functions
• Drop & Insert (D&I): 1 T1/CSU with 1 T1/CSU D&I port
• 2 T1/CSU DSO Digital Cross-Connect (DCS) with three frames maximum (0.375ms)
T1-toT1 delay
• Bandwidth allocations of voice and data
• ESF to D4 (SF) and D4 to ESF conversions for PBXs with T1 interfaces
• Time of day DS-0 mapping to optimize voice and data utilization
1.4 Dual T1/CSU Network Interfaces
Because the dual T1 network interfaces supply over 3 Mbps of useable bandwidth, the Access Bank
II SNMP is able to demultiplex the primary incoming T1 signal into 12 or 24 analog telephone circuits for connection to voice, facsimile , and high-speed V.34 modems, leaving the sec onda ry T1 port
1-2 9/24/01
Digital Data Ports
available for In te rne t connection, or for alt er nat e r outes or carriers. Doubling the bandwidth capac it y
of a conventional d igi t al c hannel bank allows th e Acc ess Bank II SNMP to dedicate t he b uil t-in V.35
DCE data port to Internet, video, or Wide-Area Network (WAN) applications, while also performing
such advanced netwo rking tas ks as Drop and Inser t (D&I), a nd DS-0 Digi tal Acces s & Cros s-connect
Switching (DACS). Both diagnostic CSUs are fully integrated, respond to all standard inband and
out-of-band network loo p codes, an d can be polle d for ANSI T1.403 one- second Perf ormance Repor t
Messages (PRMs) or AT&T 54016 Maintenance Messages over the 4 Kbps ESF Facility Data Link
(FDL).
1.5 Digital Data Ports
1.5.1 V.35 DCE Port
T o f ully uti lize th e e xtra bandwidt h suppl ied b y t he dual T1 int erfa ces, t he Ac cess Bank II SNMP has
a built-in V.35 DCE data port for connection to Wide Area Network (WAN) devices such as Internet
routers and Frame Relay Access Devices (FRADs). This high-speed serial interface supports synchronous data con necti ons fr om 56 Kbps to 1.5 36 Mbps, a ll r ates. When u sed in co njunct ion wit h the
internal BER tester , the V.35 interface is also cap able of generati ng V.54 loop codes for activating and
deactivating remote lo opba cks in DCE devi ces at the far-end. The int er veni ng t ran smission link then
can be stress tested using a selectable range of industry standard QRSS patterns (QRSS, All Zeros,
All Ones, 511, 2047, 215-1, 220-1, 202 3-1, etc.). Use of the V.35 DCE port requi r es an optional V.35
data cable.
1.5.2 RS-232 Data Port
The Control Panel of the Access Bank I I SNMP al so co nta ins a n RS-232 seco ndar y dat a port tha t can
be configured to provide a 56/64 Kbps synchronous data channel for connection to SNA cluster controllers, data multiplexers, routers, or SCADA (Supervisory Control and Data Acquisition) links.
When configured for asynchronous operation, this same RS-232 data port can also be used, alternately, to implement a point-to-point dedicated communications channel between two Acess Bank II
units at 1.2, 2.4, 4.8, 9.6, 14.4, 19.2, 28.8, 38.4, or 57.6 Kbps rates. Use of the RS-232 data port
requires an optional dual purpose RS-232 user data and management cable.
1.6 Analog Line Interfaces: FXS, & FXO, and 4-Wire E&M
To meet individual site-specific communications requirements, the Access Bank II SNMP can be
equipped with a full range of “hot-swappable” slide-insert analog line interface cards. Please contact
CAC for details and availability of these and other card options:
• The Foreign Exchange Station (FXS) 12-channel voice card delivers high quality loopstart or ground-start dial tone telephone line connections to key systems, Off Premise
Extensions (OPXs), facsimile machines, modems, PBXs and other conventional analog
telephone devices.
• The Foreign Exchange Office and Dial Pulse Termination (FXO/DPT) voice card compliments the FXS by supplying 12 st and ard loop- st art or ground-start tele phon e li ne con -
9/24/01 1-3
nections on a per channel basis from PBX office-end telephone systems to public
network T1 (DS1) services using FXO terminations. The DPT feature of this card is
especially useful in remote office or campus T1 environments where it can be used to
support one-way Direct Inward Dialing (DID) service for voice mail and call center
applications.
• A Battery Reversal FXS/Dial Pulse Origination (BRFXS/DPO) voice card is also available that provides twel ve 2-wire Loop S tart c onnection s with Tip/Ring ba ttery r eversal to
the digital T1 (DS1 line). The second function of this card is Dial Pulse Origination
(DPO), which is the functional complement to Dial Pulse Termination (DPT) provided
by the FXO/DPT voice card.
• The 4-wire E&M/Transmission Only (E&M/TO) voice card supplies 12 channels for
connecting to private line circuit s, s uch as PBX tie lines and 4-wire modems ofte n f ound
in utility, cellular, and metropolitan area networks (MANs). Each of the twelve E&M
channels can be individually programmed to support Signaling Types I, II, IV or V. This
card can also be configured to function as Channel Equipment (normal multiplexer
mode) or as Switching Equipment for back-to-back Tandem operation sometimes
referred to as “Reverse E&M” or “Pulse Link Repeater.” The Transmission Only (TO)
operating mode provides dedicated transmit and receive paths to radio and modem
equipment uncorrupted by the insertion of A/B robbed bit signaling.
All analog line interface cards greatly exceed the required analog loop range and are proven V.34
modem compatible. Using a spe cial patent-p ending feature d eveloped by Car rier Access Co rporation,
they also perform automatic impedance matching to adapt to various analog modem types and line
lengths. Over-voltage and over-current protection are individually handled on the analog interface
channel cards, as well as on the Controller. This distributes the power redundantly so that a line fault
or over-voltage on one analog channel card does not affect the operation of another.
1.7 Local and Remote Network Management
The Access Bank II SNMP has three network manage ment option s. SNMP and CLI management ar e
described in detail in Chapter 14, SNMP Management and Command Lin e Interfac e, whi le GUI management software is provided in the Access Bank II SNMP User Manual.
• Simple Network Management Protocol (SNMP) for bas ic n et work c ont rol by a Networ k
Management Station via the Ethernet 10Base-T management port.
• Command Line Interface (CLI) for complete control by a VT-100 terminal via the RS232 port, or by a Telnet terminal via the Ethernet 10Base-T port.
• Windows
control by a PC or laptop computer via the RS-232 port.
1.7.1 Local/Remote Mode Selection
The Access Bank II SNMP comes equ ipped with two sets of exte rnal DIP swit ches fo r select ing local
or remote management control. In the local hardware control mode, you can use these DIP switches
to perform self-tests for channel alignment, to select basic T1 hardware configuration parameters

Local and Remote Network Management
(AMI/B8ZS, D4/ESF), and to enabl e detec tion of standa rd D4/ESF in band loop codes by t he inte gral
CSUs. In the remote software control mode, you can use SNMP, CLI, or GUI management terminals.
1.7.2 SNMP Management
The Access Bank II SNMP:
• Supports Simple Network Management Protocol version 2 (SNMPv2) through its Ethernet 10Base-T port.
• Complies with RFC standards for for SNMPv2, Ethernet, Internet, TCP/IP, and MIB-II
network management, and T1 and RS-232 interfaces.
• Has built-in SNMPv2 Agent software providing network statistics, information retrieval
and update, trap thr esh old s, and automatic transmiss ion of t ra p dat a t o Net w ork Manage ment Stations.
1.7.2.1 Local and Remote SNMP Management
The Access Bank II SNMP provides SNMP management through its Etherne t 10Base-T port. Remote
SNMP management is possible ove r e it her of t he T1 lines within a V.35 user data segment, a s s hown

1.7.2.2 SNMP Overview
SNMP is a complete, but si mple, mec hanism f or networ k manage ment. It works by e xchanging infor mation between a Manager a nd an Agent. In this ca se, the Agent is inside t he Access Bank II/SNMP.
The Manager is a Network Management Station (NMS), which is a computer with SNMP management software such as HP OpenView
The Agent stores the information in a Management Information Base (MIB), which contains items
such as the current status of the network interface, performance statistics, and alarms.
® or Sun NetManager®.
In general, SNMP is not concerned with controlling every feature of the many different network
objects. However, SNMP is flexible enough that it can support a wide variety of private enterprise
objects with predefine d MIB data struct ures. The Access Bank II /SNMP uses the Bell core
® standard
MIB for T1 inter faces.
Manager operations incl ude simpl e “get” and “set ” comma nds to re trie ve and upda te MIB data in t he
9/24/01 1-5
Agent. Normally, the Manager polls the Agent periodically to check traffic statistics. However, the
Manager can also set th res hol ds f or tra ps. Traps sp eci fy network events and condit ions for which the
Agent automatically sends a Telnet alarm message with trap data back to the Manager.
1.7.3 Command Line Interface
The Access Bank II SNMP comes with a built-in Command Line Interface. CLI provides complete
management of all Access Bank features through any VT-100 terminal or PC connected to the RS232 port, or through any Telnet terminal connected to the Ethernet 10Base-T port.
CLI works with a communications terminal, in which you type in text and press the carriage return
key to send the message to the host. The host then responds with a log-on message, and the CLI is
ready to use.
CLI is easy to use because the Acces s Bank II SNMP provi des a lis t of menu option s to choose from.
Furthermore, context sensitive help is available to guide you through the setup process. At any time,
you can type in a qu est io n mar k (?) to obtain infor m ati on abou t what to type next or wh at commands
are available. You can also type “help” after any command to get specific help with that command.
1.7.3.1 Local and Remote CLI Management
The Access Bank II SNMP provides CLI management through its RS-232 and Ethernet 10Base-T
ports, as shown in Figure 1-2 and Figure 1-3.
For RS-232 CLI control, just connect a PC o r laptop co mputer to th e RS-232 managemen t port on t he
Access Bank II/SNMP. Then use a VT - 100 termi nal emulat ion pro gram su ch as Micros oft Hyper Terminal
®. (The default communic ations p ort sett ings are 9600, 8, 1, N.) Press th e Escape ke y to ini tiate
the link. The Access Bank will return a log-on message. If a password is required, the Access Bank
will request that you enter a password. (Units shipped from the factory do not have a password
defined, but the user is encouraged to use passwords to prevent unauthorized use.) CLI can be used
from a remote site by connecting the RS-232 port to a modem and telephone line.

1.8 Design Philosophy
The Access Bank II SNMP is manufactured by CAC according to a design philosophy based on
solid-state ove rvoltage and overc urrent pr otectio n without t he use of low-curr ent fuses (<1 A) or very
high-wattage resistor s. Thanks to thi s advan ced new tech nology, the Access Bank II SNMP complies
fully with National Electr ical Code and UL 1459 require ments for the saf ety of equipment attached to
telephone wiring without using any fuses, which dramatically improves its long-term reliability,
while greatly reducing equipment down time. As an added benefit, all items of equipment connected
to the Access Bank II SNMP are protected from transient network voltage or current surges.

2.1 About This Chapter
This chapter describes the general physical characteristics and layout of the Access Bank II - SNMP,
including its:
• Dual RJ-48C Jacks for T1 Span 1 and Span 2
• V.35 and RS-232 Digital Interface Ports
• Power Source Connector
• Standard 25-pair RJ-21X Tip & Ring Telephony Connector
• T1 Span and System Setup DIP switches
• LED Test and Status Indicators
2.2 Physical Characteristics
The Access Bank II - SNMP consists of a painted sheet steel chassis housing, nickel-plated chassis
tray and removable back plate that accepts one (or two) 7.8 inch by 13.16 inch analog line interface
daughter card(s). These analog line interface channel cards slide into the rear of the unit along rails
that guide a 64-pin DIN connector on each card to mate with a matching connector on an internal
9/24/01 2-1
Controller card. The Controller card measures approximately 4 inches by 16.25 inches and functions
as a Line Interface Unit (LIU) that integrates the two Channel Service Units (CSUs), the ringing generator, the ringback tone generator, and power converter functions. Separate Dual T1 and SNMP
daughter cards measuring 1.75 inches by 6.25 inches are each mounted on the Controller card using
support standoffs, plastic washers and screws. The Dual T1 daughter card is equipped with two standard RJ-48C 8-pin connector jacks for connecting to one (or two) T1 carrier network interface(s).
The SNMP daughter card is equipped with an RJ-45 modular jack for TCP/IP 10Base-T Ethernet
connection.
The Access Bank II - SNMP is 1.75 inches high, 17.75 inches deep, and 17 inches wide and, when
fully loaded with two analog line interface daughter cards, weighs approximately 14.5 pounds.
The Access Bank II - SNMP is des igned to operat e at an alt itude between 0 and 10,000 feet above sea
level and within a temperature range from 32
° to 104° F (0° to 40° C) and in environments with a rela-
tive humidity from 0 and 95%.
Note: For proper Access Bank II - SNMP operation outside the specified ranges,
the unit must be placed in an environmentally controlled enclosure.
2.3 Control Panel Interface Connectors
The Control Panel on the front of the chassis housing contains the following connectors and power
connection terminals shown in Figure 2-1:
• Dual T1 Span 1 and Span 2 l i ne c onne ct ion ports each equippe d wi th standard RJ-48C 8pin connector jacks.
• V.35 DCE Data port equipped with a 26-pin standard D-type subminiature connector
(female) for high-speed digital Internet WAN connections up to 1.536 Mbps.
Note: An optional V.35 da ta cable is required to ut ilize the V.35 DCE data port.
• RS-232 Remote Management port eq uipped with a standard 26-pin D-type subminiat ure
connector (female) for connection to an external PC or Hayes
-compatible modem for
local or remote configuration, management, and performance monitoring using the
Access Bank II - SNMP Remote Monito r MS W in dows-bas ed soft ware i nterf ace or c ommand line interface.
Note: An optional Dual Headed Data and Manage ment Cable is required to co nnect
to the primary Management and secondary Data leads for simultaneous local or
remote management and asynchronous or synchronous data connections.

Control Panel DIP Switches
• Three-position DC power t er minal input for c onne ct ion to the 115 Vac to -48 Vdc Power
Converter Cube, or to a customer-supplied external -48 Vdc battery power source.
• Tip & Ring Analog Interface equipped with standard 25-pair Telephony Connector
(female) for connection to key systems, facsimile devices, modems and PBXs.
The ABII Control Panel is equipped with an interface connector for accessing the embedded SNMP
agent.
2.4 Control Panel DIP Switches
The Access Bank II - SNMP Control Panel also contains a 10-pos ition T1 Span Setup DIP switch that
is used for individually configuring each of the two T1 network interfaces. There is also a 4-position
System Setup DIP switch for selecting between Local or Remote modes of management and activating and deactivating alarm cut-off. The locations of these DIP switches are shown in Figure 2-1. As
an aid to setting up the these DIP switches, a convenient installation guide is silk screened onto the
chassis housing and reprinted here in Figure 2-2.
2.5 LED Test and Status Indicators
There are five LED indicators that display the current performance and test status of the dual T1
spans lines and V.35 digital interface. Figure 2-1 shows the locations of these LEDs on the Access
Bank II - SNMP front Control Panel. How to interpret the current state of each LED indicator is silk
screened onto the chassis housing and reprinted here in Figure 2-2.
