Canadian Equipment Limitations

Notice: The Canadian Industry and Science Canada label identifies certified equipment. This certification means that the equipment meets certain telecommunications network protective, operational, and safety requirements. 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. The equipment must also be installed using an acceptable method of connection. In some cases, the company’s inside wiring associated with a single line individual service may be extended by means of a certified connector assembly (telephone extension cord). The customer should be aware that compliance with the above limitations may not prevent degradation of service in some situations.

iv 61200290L1-1G

MX2800 M13 Multiplexer System Manual

Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.

Users should not attempt to make such connections themselves, but should contract the appropriate electric inspection authority or an electrician, as appropriate.

The Load Number (LN) assigned to each terminal device denotes the percentage of the total load to be connected to a telephone loop which is used by the device, to prevent overloading. The termination on a loop may consist of any combination of devices subject only to the requirement that the total of the Load Numbers of all devices does not exceed

100.

SECTION 1, PRODUCT OVERVIEW

Section 1

Product Overview

1. INTRODUCTION

The MX2800 is an M13 multiplexer that consolidates T1 and E1 signals into a T3 circuit. This unit provides a cost-effective, versatile tool for combining independent T1s, E1s, or a combination of the two over the same T3 circuit.

The MX2800 houses two hot-swappable controller cards which provide 1:1 redundancy for the T1 and T3 signals, as well as the T3 connections.

Embedded simple network management protocol (SNMP) and Telnet are available through the modem port using serial line internet protocol/point-to-point protocol (SLIP/PPP) or through the 10Base-T Ethernet port. Using the Management Information Base II (MIB II), RFC 1407 standards, and an ADTRAN enterprise MIB, the MX2800 can be configured, monitored, and diagnosed with standard SNMP network management programs such as Hewlett Packard’s HP OpenView Spectrum

. In addition, the SysLog Host Daemon allows remote monitoring, collecting, and logging of

MX2800 events in realtime. This information is useful during installation setups and/or troubleshooting.

Complete configuration, loopbacks, and performance monitoring are available through SNMP, Telnet, or a VT100 terminal interface. This connection can be made via Ethernet, a local EIA-232 link, or through the built-in V.34 modem. The modem can dial out a “cry for help” for units located in unmanned facilities. The MX2800 is designed for installation in a 19-inch or 23-inch rack.

• NEBS Level 3 compliant

NOTE

Information regarding the built-in modem applies to the part numbers

4202290L1, 4202290L2, 4202290L3, and 4202290L4.

2. CONTROLLER CARD 1:1 REDUNDANCY

The MX2800 supports two hot-swappable controller cards which provide 1:1 redundancy for the T1 and T3 signals and connections. With two cards installed, the MX2800 can recover from circuit or network failure. Refer to Section 7, Circuit and Network Redundancy for more information.

3. T3 OVERVIEW

A T3 provides the same bandwidth as 28 T1s. Typically, leasing a T3 line costs the same as eight to ten T1s. Using the MX2800, a single T3 can provide internet connectivity and voice (local and long distance) to individual sites across up to 28 individual DSX-1s. T3 is also extremely cost effective for backhauling local and long distance voice.

4. SNMP

The MX2800’s embedded SNMP feature allows the unit to be accessed and controlled by a network manager through the 10Base-T local area network (LAN) port. The MX2800 supports the MIB-II standard, RFC 1213, and the ADTRAN Enterprise Specific MIB.

NOTE

MIB files are available from ADTRAN in the support section of the

ADTRAN Web page at www.adtran.com.

The term SNMP broadly refers to the message protocols used to exchange information between the network management system (NMS) and the managed devices, as well as to the structure of device management databases. SNMP has three basic components: the network manager, the agent, and the MIB.

Network Manager

The network manager is a set of control programs that collect, control, and present data pertinent to the operation of the network devices. These programs reside on a network management station.

1-2 61200290L1-1G

MX2800 M13 Multiplexer User Manual Product Overview, Section 1

Agent

The agent is a control program that resides in every network device. This program responds to queries and commands from the network manager, returns requested information or invokes configuration changes initiated by the manager, and sends unsolicited traps to the manager.

MIB

An MIB is an industry standard presentation of all status and configuration parameters supported by a network device.

5. TELNET

Telnet provides a password protected, remote login facility to the MX2800 that allows a remote user to control the MX2800 through the terminal menus. Only one Telnet menu session may be active at a time.

6. TL1

Transaction Language 1 (TL1) is an ASCII-based language that supports both command-response and autonomous (NE) message generation. Commonly, TL1 is used over an X.25 packet network but is completely independent of any physical layer protocols. For the MX2800, TL1 is implemented as a Telnet session running over Ethernet or PPP. Currently, up to eight TL1 Telnet connections can be active at a time.

7. AVAILABLE OPTIONS

The following optional equipment is available for use with the MX2800. Contact a local distributor or the ADTRAN Sales Department for more information. Refer to Appendix F, Warranty for contact information.

Breakout Panel (P/N 1200291L1)

The optional breakout panel connects to the MX2800 and provides 28 RJ connectors for the individual T1s/E1s. Shipment includes two six-foot, 64-pin to 64-pin amphenol cables which allow direct cabling to the MX2800. Refer to Connecting the Breakout Panel on page 2-5 for more information.

10. Care should be taken not to upset the stability of the equipment rack after installation is complete.

CAUTION

Use copper conductors only for DC power and ground connection.

5. RACKMOUNT INSTALLATION

The MX2800 can be mounted into a standard 19-inch or 23-inch equipment rack. Follow these steps to mount the unit into a rack:

1. Install the mounting flanges on each side of the MX2800 at one of the three available positions.

CAUTION

Be sure to install the flanges with the screws provided.

2. After the flanges have been installed, position the MX2800 at the correct location within the rack and secure the mounting flanges to the mounting rails of the rack.

3. Make all network, DTE, and power connections to the rear of the unit. Refer to Power Up on page 2-2 for more information on making the DC power connection.

4. Using the 8-position modular to DB-9 female connector and the 8-pin to 8-pin modular cable, connect a VT100 terminal device to the

8. REPLACING OR INSTALLING CARDS

The MX2800 is designed with hot-swappable controller cards and power supplies. To replace or install a controller card or power supply, remove the front cover of the MX2800 with a phillips head screwdriver. Once the front of the MX2800 has been removed, the power supply and controller card slots will be visible. The two power supplies are located at the left of the chassis, and the controller cards are stacked on the right side of the chassis. To remove a card, use the locking lever(s) to pull the backplane connector away from the backplane. Once the backplane connector has been disconnected, carefully pull the card straight out of the chassis. To replace or install a card, line up the card with the guide grooves and carefully insert the card into the chassis until the backplane connector reaches the backplane. Finally, use the locking levers to seat the card all the way into the slot of the chassis. Once all cards have been replaced or installed, replace the front cover of the MX2800. Figure 2-11 shows how to remove and replace the front cover.

Remote Loopbacks

The following four options are available for remote loopbacks:

• FEAC/C-BIT the DS3 Far End Alarm and Control (FEAC) channel and/or DS2-level C bits. This mode is valid in

C-BIT and M13 framing formats.

both

• FEAC is used to allow the MX2800 to respond only to remote loopback requests received over the DS3 FEAC channel. This mode is valid only when using C-BIT framing. In this mode, DS2 C-bit loopbacks will be ignored.

• C-BIT is used to allow the MX2800 to respond only to remote loopback requests received over DS2 C bits. This mode is available when operating in either C-BIT or M13 framing. In this mode, FEAC loopbacks received when operating in C-BIT framing will be ignored.

• Disabled is used to ignore all out-of-band loopback requests (FEAC and DS2 C-BIT). When is selected, the MX2800 will still respond to individual T1 in-band CSU/NIU loopbacks if so configured in the T1/E1 Loopback Detection menu.

Protection Configuration

The MX2800 houses two controller cards for 1:1 protection against hardware failure. The two cards can also provide network protection, supporting two T3 circuits simultaneously. The selections in this menu allow customizing the unit’s protection setup.

Active Controller

This field displays A or B, indicating the active controller card. This setting can be used to force the controller cards to switch. For example, if controller card A is active and B is selected, a switch-over occurs immediately.

Network Protection

This field enables or disables the unit’s ability to automatically route information to the backup T3 in the event of a primary T3 failure. If enabled, all information is automatically routed to the backup T3. If disabled, the stand-by controller protects against failures of the active controller.

Maximum Switch Threshold

The value entered in this field determines the number of times per hour the unit is allowed to switch between controller cards. If, in an hour, the cards switch more than the Maximum Number of Switches, the unit issues a trap and stops switching cards for the next 24 hours. Refer to Trap Descriptions on page 3-22. The default setting is three times an hour. This count may be cleared by clearing

Miscellaneous

The Miscellaneous menu selections are used to configure the Loopback Timeout and Shutdown Stand-by settings. Descriptions of these settings are explained below.

Loopback Timeout

The Loopback Timeout option is used to set the loopback timeout to one of the following:

• Disabled

•1 min.

•5 min.

• 10 min.

• 15 min.

• 30 min.

• 45 min.

•1 hr.

• 120 min.

Shutdown Stand-By

The Shutdown Stand-by option causes the system to disable the standby controller card, thus making it unavailable for protection switches. Once this option has been selected and the standby controller has been shut down, the option changes to Reset Stand-by. Selecting this option resets and reactivates the standby controller, thus making it available for protection switching.

DS2 Configuration

The MX2800 can individually frame each of the seven DS2 streams in M12 (four T1s) or G.747 (three E1s) format. When set to M12 (4xT1), the four T1s for the selected group are framed per ANSI T1.107. When set to G.747 (3xE1), the first three T1/E1 ports of the selected group are framed per CCITT G.747 into the DS3 stream. The fourth T1/E1 port of the selected group is not available in this mode. Any combination of M12 (4xT1) and G.747 (3xE1) is allowed.

MX2800 M13 Multiplexer User Manual Configuration, Section 3

Management Options

The Management options sets the fields that allow SNMP, Telnet, or VT100 interface access. The options are listed below.

Local IP Address

This field is used to enter the MX2800 IP address. This IP address applies to the LAN or modem port when configured for SLIP/PPP. This address is available from a network administrator.

Gateway IP Address

This field is used to enter the gateway IP address of the MX2800. This address is necessary only if the MX2800 and the network manager are connected through a gateway node. If an IP packet is to be sent to a different network, the unit sends it to the gateway.

Subnet Mask

This field is used to enter the subnet mask of the MX2800. This address is available from a network administrator.

Modem Remote IP Address

This field is used to enter the IP address of a server that accesses the MX2800 via a modem over PPP or SLIP. This option is available only if the Management Port is set to LAN + MODEM or DS3 + MODEM.

Management Port

This field is used to assign the management port as either LAN, MODEM, LAN+MODEM, DS3, or DS3+MODEM. The Modem setting applies only to units equipped with an internal modem.

Forward IP to Remote DS3

This field is used to enable or disable the IP forwarding feature that allows IP access to a remote MX2800 across the DS3 channel. With this feature, the far-end MX2800 appears as if it is on the same LAN as the near-end MX2800. To access any IP related feature on the far-end unit, address packets to the IP address of the far-end unit.

NOTE

If the near-end and far-end MX2800s are currently on the same LAN, it is important to configure the far-end MX2800 Management Port option for DS3 or DS3 + MODEM before enabling Forward IP To Remote DS3 on the near-end unit. Doing so prevents multiple MAC addresses from being associated with the same IP address in the networks ARP tables.

61200290L1-1G 3-17

Section 3, Configuration MX2800 M13 Multiplexer User Manual

NOTE

The DS3 must be up and running error-free and using C-Bit framing (this feature will not work with M13 framing). The Management Port option for the near-end unit (one connected to the Ethernet LAN) must be set to either LAN or LAN + MODEM. A valid IP Address, Subnet Mask, and Default Gateway must be entered for the near-end unit.

DS3 Remote IP Address

If Forward IP to Remote DS3 is Enabled, set the DS3 Remote IP Address to a valid IP address on the same subnet as the near-end unit. All packets that are sent to this IP address will be forwarded across the DS3 channel to the far-end unit.

NOTE

The IP Address of the remote unit must be the same as the one that is entered for the DS3 Remote IP Address in the near-end unit's menus. The Management Port option for the far-end unit must also be set to DS3 or DS3+MODEM to be managed remotely over the DS3. The Subnet Mask and Default Gateway do not need to be set in the far-end unit's menus. The DS3 Remote IP Address must be on the same subnet as the Local IP Address.

DS3 IP MTU

This field is used to select the maximum IP datagram size (in bytes) for the IP forwarding link over the DS3. This option should be left at it default and preferred value of 260. If and only if the device on the other side of the DS3 facility is an ADTRAN device that also has this option, then both side can be set to 1500 to avoid fragmentation of large packets. Otherwise, leave the setting at 260 to avoid lost packets.

Dialup Options

This field is used to configure the dialup capabilities of the MX2800. See Figure 3-13. These options apply only to units equipped with an internal modem.

3-18 61200290L1-1G

MX2800 M13 Multiplexer User Manual Configuration, Section 3

Figure 3-13. Dialup Options Menu

Primary and Secondary Phone Numbers

When the MX2800 dials out to send a trap, it first dials the Primary Phone Number. If the call is unsuccessful, it tries the Secondary Phone Number. Attempts between the two numbers continue until a call is established and the trap is reported (or until each number’s maximum for redial attempts is reached). Refer to

Maximum Redial Attempts on page 3-19.

Initializing String

The AT command entered in this field is used to initialize the modem. Normally, this field should be left at the default setting (ATZ).

Dial String

The AT command entered in this field causes the modem to dial out. Normally, this field should be left at the default setting (ATDT).

Maximum Redial Attempts

The MX2800 attempts to establish a call the number of times entered in this field. If a successful call is not established after the final attempt, the MX2800 discards the trap messages.

Idle Timeout

After establishing a call and sending trap messages, the MX2800 remains online for the amount of seconds entered in this field. If the field is set to 0, the unit hangs up as soon as the trap is sent.

61200290L1-1G 3-19

Section 3, Configuration MX2800 M13 Multiplexer User Manual

Connection Timeout

The MX2800 waits for a connection for the number of seconds entered in this field. Timing begins as soon as the dial command is issued. This field must be set for greater than 20 seconds.

Pause Between Calls

The MX2800 waits between redial attempts for the number of seconds entered in this field.

Dialout On Trap

This field is used to enable or disable the MX2800’s ability to dial out to report traps. Modem Mode configured for VT-100 reports error conditions in plain ASCII with the following information:

• The Unit ID value programmed in the Equipment Identification portion of the System Management screen. Refer to System Management on page 3-16.

• A trap code indicating the error condition

• A text description of the fault

• The date and time when the error was logged

When Modem Mode is configured for PPP or SLIP, the MX2800 logs into the PPP/SLIP host and reports the error conditions to the hosts designated under Trap IP Addresses. Refer to Trap IP Addresses on page 3-21.

Answer on Ring

This option enables or disables the MX2800’s ability to accept incoming calls. If enabled, incoming calls are automatically answered by the MX2800, allowing remote performance of management functions.

Modem Mode

This field is used to select the Modem port function for the desired application (VT-100, PPP, or SLIP). The Modem port, located on the rear panel of the MX2800, provides a telephone line (POTS) for connection to the internal V.34 modem. This setting applies only if the Management Port is set to Modem. Refer to Management Port on page 3-17.

Modem Baud Rate

This option is used to set the maximum operating speed in bps of the Modem port:

•1200

•2400

Trap Community Name

This field is used to enter the identification string used for trap management. This string accompanies all traps transmitted by the MX2800.

System Name

This value is equivalent to the sysName item defined in RFC1213. The value is an administrativelyassigned name for the managed node. By convention, this is the node's fully-qualified domain name.

Network Date/Time Option

The MX2800 is capable of having the date and time provisioned from a remote server using one of two supported protocols: SNTP version 3 (per RFC1769) and Network Time (per RFC868).

Several options are available for provisioning this feature, all of which are accessible only via menus by users with Admin-level privileges. These options reside in the System Management menu.

State

This option sets the mode or protocol used to retrieve the date and time from the server. Possible values are Disabled, SNTP, and Net Time. When the State option is set to Disabled, the user should explicitly set the date and time locally (via menus, TL1, or SNMP). If the State option is set to SNTP or Net Time, then the product prevents any attempt to set the time locally. The default value is Disabled.

Server IP Address

This option sets the IP address of the server to be queried for the date and time.

Refresh Period

This option sets the length of time between queries to the server. The available values range are as follows:

• 1 minutes interval

• 5 minutes interval

• 10 minutes interval

• 15 minutes interval (default)

• 20 minutes interval

• 25 minutes interval

• 30 minutes interval

• 35 minutes interval

• 40 minutes interval

• 45 minutes interval

• 50 minutes interval

• 55 minutes interval

• 60 minutes interval

DST Automatic Adjustment

This option sets automatic adjustment for North American daylight saving time. Available values are Enabled and Disabled. The default value is Enabled. This automatic adjustment is performed only in association with responses from the server. The automatic adjustment does not take place if the State option is disabled and/or if the server cannot be contacted.

Local Time Zone

This option sets the time zone in which the MX2800 unit is located. Possible values consist of North American time zones from Hawaii-Aleutian Standard Time to Atlantic Standard Time. The default value is Eastern Standard Time.

NOTE

The MX2800 processes only the Transmit Timestamp value of all SNTP response messages. Other constructs supported by the protocol (such as root delay, root dispersion, authentication, etc.) are not processed by the MX2800.

System Security

User Account Management

This option is used to enter up to 15 user accounts. Each user account is assigned a username, password, and privilege level. Usernames and passwords are not case sensitive but must be 12 characters or less. Each user account is assigned a privilege level to provide the option of limiting a user's access to the MX2800. The four privilege levels are listed below.

Guest

A user with this read-only privilege level can view almost all menu items on the console interface menus and can perform a limited number of TL1 commands, none of which can alter the product's configuration.

Interface

A user with write-access privilege level can configure items related to the network interface and T1/E1 interface but can not initiate loopbacks and view and/or alter several system-level items such as LAN configurables.

RADIUS Authentication

The MX2800 is capable of communicating with a RADIUS server for authentication of menu users and TL1 users. The RADIUS authentication support is implemented per RFC2865. User account information in the onboard user database will remain intact when the MX2800 is upgraded to support authentication via RADIUS.

Several options are available for provisioning RADIUS authentication features, all of which are accessible only via menus and by users with Admin-level privileges.

RADIUS State

This option sets the RADIUS authentication capabilities as either Enabled or Disabled. The default value is

Disabled.

When the RADIUS State value is Enabled, the following behavior applies when a user enters a username and password at the MX2800. The MX2800 first authenticates the username and password against the local user database. If local authentication succeeds, then access is granted to the MX2800 with the privilege level assigned for that account in the onboard database. Local authentication is considered successful if both the username and password are authenticated, regardless of the privilege level (including Disabled).

If local authentication does not succeed, then the username and password are authenticated against the RADIUS server. If the RADIUS authentication succeeds, then access to the MX2800 is granted with the RADIUS Privilege Level set by the user. If the RADIUS authentication does not succeed, which includes the case where the MX2800 does not receive a response from the server, then the user is denied access to the MX2800.

Regardless of whether the RADIUS State option is Enabled or Disabled at the MX2800, each user account that exists in the local user database may be assigned one of the defined privilege levels for the MX2800 (Disabled, Guest, Interface, Test, or Admin). Only a user with the Admin privilege level can access the local database and the RADIUS options.

61200290L1-1G 3-27

Section 3, Configuration MX2800 M13 Multiplexer User Manual

Usernames and passwords stored in the local user database are each limited to 11 ASCII characters. Usernames and passwords authenticated via RADIUS may each have up to 63 ASCII characters.

When RADIUS authentication is disabled, safeguards are in place that will prevent an Admin-level user from deleting all Admin-level accounts in the onboard user database. When RADIUS authentication is enabled, an Admin-level user who was authenticated through RADIUS will be allowed to delete all of the onboard accounts. This will be allowed to avoid some potential security concerns.

Safeguards will exist that will prevent certain combinations of options involving RADIUS and the local user database that would effectively remove all means of accessing the MX2800 with Admin privileges.

The recovery mechanism for gaining access via the challenge password (ADTRANPLEASEHELP) is supported regardless of whether the RADIUS authentication option is enabled or disabled. When a user enters this password, the MX2800 issues a unique challenge sequence that requires a response provided by ADTRAN Tech Support for access to the unit.

Local user accounts and passwords for the MX2800 are not case-sensitive. However, case is preserved for both username and password when authenticating through RADIUS. The TL1 input message specification limits the characters that may be sent as part of a TL1 command, unless the string is enclosed in double quotes. This is important when RADIUS authentication is used for authenticating TL1 sessions. Passwords or usernames with special characters must be placed in double quotes in the ACT-USER command. If double quotes appear inside the TL1 username or password, each double quote character must be immediately preceded by the backslash character to avoid confusion with the double quotes surrounding the username or password.

The MX2800 supports Challenge response messages from the RADIUS server regardless of whether the login attempt is made via menus or TL1. If a Challenge response is received from the server, then the user is prompted for additional information. The nature of this additional information is application-dependent. When the Challenge response is received during an attempt to log in via TL1, then a PLNA TL1 response is returned to the user and the Challenge message is provided in the TL1 comment field.

Server IP Address

This option sets the IP address of the server to be queried for authentication. The default value is a null IP address. One IP address is supported.

UDP Port

This option sets the UDP port of the server. The default value is 1812.

Privilege Level

This option sets a single privilege level that applies for all users that are granted access via remote authentication. The possible values are

Disabled, Guest, Interface, Te st , and Admin. The default value is Guest.

Refer to the appropriate MX2800 documentation for explanations of these privilege levels.

Shared Secret Visibility

This option sets the visibility of the Shared Secret value as displayed in the provisioning menu for RADIUS authentication options. The possible values are

Invisible, the Shared Secret value is masked with asterisk characters. The default value is Invisible.

Visible and Invisible. When this option is set to

3-28 61200290L1-1G

MX2800 M13 Multiplexer User Manual Configuration, Section 3

Shared Secret

This option sets the shared secret that is used during the process of authenticating via the RADIUS server. This value is a case-sensitive ASCII character string that has a maximum length of 63 ASCII characters. The default value is a null string.

Response Timeout

This option sets the number of seconds the MX2800 will wait for a response before retransmitting the request.

Maximum Retries

This option sets the maximum number of retransmissions of an authentication request that the MX2800 will attempt in the absence of a response from the server.

NOTE

After new software has been downloaded to the MX2800 system, a condition known as a “software version mismatch” exists on the active card. The currently running software version is different from the version of the new software that was just programmed into the card's nonvolatile memory. This condition occurs because a manual card reset is necessary for the card to begin running the new software. If the software version being run by the system before the upgrade began was 2.00 or higher, this mismatch will be indicated by a TL1 standing condition (condition code PROGFLT) and a repeating message displayed at the bottom of all menu screens. This is not a service-affecting condition; however, it is recommended that the download process be completed by resetting the active card as soon as it is practical. Doing so assures that all improvements in the new software are fully available.

Configuration Transfer

Select Config Transfer from the Utilities menu to transfer files to and from a TFTP server. The Config Transfer option is used to save the MX2800 configuration as a backup file, ensuring that the same configuration can be used with multiple MX2800 units. Only one configuration transfer session (upload or download) can be active at a time.

24 Hour Alarm History

The MX2800 keeps track of alarms for both the near and far ends of the network. View alarm history information in one of the three time period selections, or view a cumulative alarm count. Information in these fields is for the given time period since the last reset. The cumulative alarm count continues indefinitely until Clear All DS3 Alarm Counts is selected. See Tabl e 5 -1 for a list of alarm counts. See Figure 5-3 on page 5-3 and Figure 5-4 on page 5-4 for examples of alarm screens.

Table 5-1. Alarm Counts

Condition Description

LOS Number of times the unit has lost the receive signal.

LOF Number of times the unit has detected a loss of framing from the network.

AIS Number of times the unit has received an AIS (blue) alarm condition from the net-

work. AIS alarms occur when consecutive 1010s are received in the information bits. This indicates that there is a transmission fault located either at or upstream from the transmitting terminal.

RAI Number of times the unit has received an RAI (yellow) alarm from the network.

This alarm is a signal sent back toward the source of a failed transmit circuit. The X-bits (X1 and X2) are set to zero.
