Important Regulatory Information

Government Requirements

Certain governments require that instructions pertaining to connection to the telephone network be included in the installation and operation manual. Specific instructions are listed in the following sections.

United States Notice to Users of the Telephone Network

This equipment complies with Part 68 of the FCC rules. On the equipment is a label or silk screened text that contains, among other information, the FCC registration number for this equipment. If requested, please provide this information to your telephone company .

If your T1 equipment causes harm to the telephone network, the telephone company may discontinue your service temporarily. If possible, they will notify you in advance. But if advance notice is not practical, you will be notified as soon as possible. You will be advised of your right to file a complaint with the FCC.

Your telephone company may make changes in facilities, equipment, operations, or procedures that could affect the proper operation of your equipment. If so, you will be given advance notice so as to give you an opportunity to maintain uninterrupted service.

No repairs may be performed by the user. Should you experience dif ficulty with this equipment, refer to the

Sales and Service Information

Make the T1 network connection using a Universal Service Order Code (USOC) type RJ48C jack for single-line installations and type RJ48H jack for multiline installations. Specify both the Service Order Code 6.0N, as well as the proper Facility Interface Code, to the telephone company when ordering the T1 line.

The Federal Communication’s Commission (FCC) requires that the end user (person responsible for operation and maintenance of the equipment) file an affidavit with the local exchange carrier when connecting unprotected Customer Premises Equipment (CPE) to the public T1 network. The T1 equipment is considered an unprotected CPE because the analog through transmission gain paths, associated with the voice cards, are user adjustable. This affidavit is required whenever digital terminal equipment without encoded analog content and billing protection is used to transmit digital signals containing encoded analog content which is intended for eventual conversion into voice-band analog signals and retransmitted on the network. This affidavit shall affirm that either no encoded analog content or billing information is being transmitted or that the output of the device meets Part 68 encoded analog content or billing protection specifications. An affidavit form has been provided for your convenience.

Description

9161-A2-GH30-31 July 1998

Important Regulatory Information

WARNING:

In order to maintain compliance with Part 68, FCC Rules and Industry Canada’s CS-03 Specification, the transmit gain settings associated with the E&M, FXO and FXS V oice APMs must be set to ensure that:

— The absolute signal power of the encoded analog signals, other than live voice and network control

signaling, will not exceed –12 dBm when averaged over any 3-second interval.

— For network control signals (such as DTMF), the level will not exceed –3 dBm.

The E&M, FXO and FXS voice lines are to be connected to locally attached equipment only . Under no circumstances should voice lines be used on exposed (outside) plant lines.

After the telephone company has installed the requested service and jack, you can connect the equipment to the network. An FCC-compliant telephone cord and modular plug are provided with this equipment. This equipment is designed to be connected to the telephone network or premises wiring using a compatible modular jack that is Part 68 compliant.

Canada Notice to Users of the Canadian Telephone Network

The Industry Canada label identifies certified equipment. This certification means that the equipment meets telecommunications network protective, operational and safety requirements as prescribed in the appropriate Terminal Equipment Technical Requirements document(s). The Department does not guarantee the equipment will operate to the user’s satisfaction.

Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company.

About the T1 Access Mux

 Hot Swapping. Provides the ability to insert and remove APMs without

powering-down the housing, and without having to reconfigure the cards each time they are moved.

The APM configurations travel with the NAM. When an APM is inserted or removed, the NAM senses that an APM has been inserted or removed, and can automatically make the appropriate changes to screens, configuration options, and MIB objects.

— When an APM is inserted in a previously unassigned slot, the T1 access

unit configures the APM using the factory default configuration.

— When the same type of APM is inserted into a previously assigned slot,

the T1 access unit uses the configuration for the APM that previously occupied the slot; the APM does not have to be reconfigured.

— When another type of APM is inserted into a previously assigned slot, an

alarm and trap are generated for the slot. If accepted, the factory default configuration is loaded for the new APM type; if rejected, the new APM is ignored and the previous configuration is retained.

 The NAM can be removed without powering down the unit; however, all

system functionality is lost. When a NAM is removed and inserted into another housing, it applies the NAM’s configurations from the previous housing to the current housing.

— If the NAM is moved from a 2-slot housing to a 5-slot housing, the

operator can use the configuration of the APM in slot 02 of the previous housing. APMs in slots 03 – 05 will be configured with the factory default settings.

— If the NAM is moved from a 5-slot housing to a 2-slot housing, the factory

default configuration options are loaded.

— If the NAM is moved from a 2-slot or a 5-slot housing to a 14-slot

housing, the factory default configuration options are loaded.

 Multiple User Interfaces. Provides multiple means for configuring,

operating, managing, and monitoring the unit.

Menu-Driven User Interface.

—

Provides an easy to use, menu-driven interface for configuring and managing the T1 access unit locally or remotely.

Access to the user interface can be through an async terminal (or other VT100-compatible terminal), PC emulation, modem, or a Telnet session.

LED (Light-Emitting Diode) Monitoring.

—

Provides LEDs on the circuit card

faceplates that indicate the status of the card’s operation.

 Network Management Capability.

About the T1 Access Mux

 Multiple Management Paths. Provides multiple methods for sending/

receiving management data.

—

Embedded Data Link (EDL)

. Provides a path for management data over a performance channel between two nodes. The performance channel uses 8 Kbps of bandwidth, and is embedded in the synchronous data channel. If you choose this method, you must have a Sync Data port.

Direct Data Link (DDL)

—

. Provides a path between two nodes over the T1/FT1 link itself, embedding the management data in the T1 bundle. The management data always uses 1 DS0 (64 Kbps).

Facility Data Link (FDL)

—

. Provides the management path over the FDL of the DS1 extended superframe (ESF). Using this method does not use any customer data bandwidth, but requires end-to-end connectivity. If you select this method, you may need to work with your service provider to ensure that ESF framing is used and the required FDL management path exists end-to-end.

COM Port

—

. Provides a physical path over the communications port/interface for local user interface access or network IP connectivity data management.

 IP Connectivity. Supports connectivity within an IP network for up to 300 IP

host and/or network routes. Using the four management paths described above, provides IP routing for SNMP, Telnet, and file transfer protocol (FTP) messages connectivity without requiring direct connections.

 DSX-1 Drop and Insert port(s) allows DTEs/PBXs that support the DS1

signal format to share the T1 network with other high-speed equipment. One DSX-1 port is provided on the 9161 T1 NAM. The DSX APM (for use with the 9261 T1 NAM) provides two drop/insert ports.

 Alarm and Fault Condition Indication. Provides the capability of attaching

a terminal or printer to display/print alarm messages. Alarms or traps that are generated include: power supply, loss of signal, out

of frame, alarm indication signal, excessive error rate, primary and secondary clock failure, yellow alarm signal received, misconfiguration, and APM failure.

About the T1 Access Mux

 Extensive Statistics Gathering. Provides a complete view of the network’s

and each data port’s performance through the statistical data collected from those interfaces to assist in determining the duration of a condition or event.

— A total of 96 intervals (24 hours) of user and Telco statistical data is kept,

seven per screen page, over a 24 hour period, in 15-minute intervals.

— A total of 32 intervals (8 hours) of Synchronous Data Port statistical data

is kept, over an 8 hour period, in 15-minute intervals.

— Quick and easy access to any of the 96 sets of statistics is provided by

selecting a specific interval or occurrence timeframe. (Specifying an occurrence timeframe is useful when you know about what time a specific event occurred.)

— You can select a set of statistics to display at the following times:

following an event, preceding an event, immediately preceding and following an event, or only those statistics that occurred at or after the event that is the specified interval or time.

— Statistics collected measure or count the following: errored, unavailable,

severely errored, and bursty errored seconds, as well as controlled slip seconds and loss-of-frame counts. In addition, yellow alarm, loss of signal, excessive error rate, frame-synchronization bit error, and line-code violation counts are kept for each 15-minute interval.

— The worst interval for each statistic is provided as an additional aid in

selecting statistical information surrounding trouble spots.

 Configuration Upload/Download and Software Download Capability.

Provides quick, cost-effective software upgrades, and quick transfer of configuration options to and from nodes using a standard file transfer protocol (FTP).

 Security. Provides multiple levels of security, which prevents unauthorized

access to the unit. Security can be controlled by:

— Disabling any form of access to the unit. — Requiring logins (login ID/password/access level combinations), with

three access levels to select from: read-only, limited-access, and full-access.

— Enabling SNMP management, and specifying a community name and

access level Read or Read/Write.

— Enabling SNMP management, and specifying the IP addresses of only

selected NMSs.

 Redundant power supply. Redundant load sharing supply (both AC and DC

versions available) for the 5-slot housing and the access carrier. Protects the system from a service outage if one power supply fails.
