Note The Cisco AS5350 and Cisco AS5400 universal gateways were formerly known as the Cisco AS5350 and Cisco AS5400 universal access servers.
Feature Overview
The universal port dial feature card (DFC) is a hardware card that processes voice and data services port technology for the Cisco AS5350 and Cisco AS5400. The ports on the Universal Port DFC support multiple types of service including modem, digital, voice, and fax. Ports can be aggregated at the slot level of the Universal Port module, the Service Processing Element (SPE) level within the Universal Port module, and the individual port level.
Note You can find the NextPort DFC data commands for the Cisco AS5350 at http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5350/alexfeat/121_3xq/nextport/alxnxpt.htm. You can find the NextPort DFC data commands for the Cisco AS5400 at http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121newft/121t/121t3/nextport/dtspecmd.htm.
Instead of the traditional line/modem one-to-one correspondence, lines are mapped to an SPE that resides on the Cisco AS5350 and Cisco AS5400 universal port DFC. Each SPE provides modem services for six ports. Busyout and shutdown can be configured at the SPE or port level. The Universal Port DFC introduces the slot and SPE software hierarchy. On the Cisco AS5350 and Cisco AS5400, the hierarchy designation is slot/spe. The Universal Port DFC slot is defined as a value between 1 and 7. Slot 0 is reserved for the motherboard. Each Universal Port DFC provides 18 SPEs. The SPE value ranges from 0 to 17. Because each SPE has six ports, the Universal Port DFC has a total of 108 ports. The port value ranges from 0 to 107.
The universal port DFC performs the following functions:
•Converts pulse code modulation (PCM) bitstreams to digital packet data
•Forwards converted and packetized data to the main processor, which examines the data and forwards it to the backhaul egress interface
•Supports all modem standards (such as V.34 and V.42bis) and features, including dial-in and dial-out
SPE Firmware
SPE firmware is automatically downloaded to a Universal Port DFC from the Cisco AS5350 and Cisco AS5400 when you boot the system for the first time, or when you insert a Universal Port DFC while the system is operating. When you insert DFCs while the system is operating, the Cisco IOS image recognizes the cards and downloads the required firmware to the cards.
The SPE firmware image is bundled with the universal gateway Cisco IOS image. The SPE firmware image uses an auto detect mechanism, which enables the Universal Port DFC to service multiple call types. An SPE detects the call type and automatically configures itself for that operation. For further information on upgrading SPE firmware from the Cisco IOS image, see the "Configuring SPEs to Use an Upgraded Firmware File" section.
The firmware is upgradable independent of Cisco IOS upgrades, and different firmware versions can be configured to run on SPEs in the same Universal Port DFC. You can download firmware from the Cisco Systems Cisco.com File Transfer Protocol (FTP) server. For further information on upgrading SPE firmware from the Cisco.com FTP server, see the next section, Upgrading SPE Firmware from the Cisco.com FTP Server.
Upgrading SPE Firmware from the Cisco.com FTP Server
You can upgrade SPE firmware from the Cisco.com FTP server by doing the following:
•Downloading SPE Firmware from the Cisco.com FTP Server to a Local TFTP Server
•Copying the SPE Firmware File from the Local TFTP Server to the SPEs
Downloading SPE Firmware from the Cisco.com FTP Server to a Local TFTP Server
Note You must be a registered Cisco.com user to log in to the Cisco Software Center.
You can download software from the Cisco Systems Cisco.com FTP server using an Internet browser or using an FTP application. Both procedures are described.
Using an Internet Browser
Step 1 Launch an Internet browser.
Step 2 Bring up the Cisco Software Center home page at the following URL (this is subject to change without notice):
http://www.cisco.com/kobayashi/sw-center/
Step 3 Click Access Products (under Cisco Software Products) to open the Access Products window.

Step 6 Click the SPE firmware file you want to download, and then follow the remaining download instructions. If you are downloading the SPE firmware file to a PC, make sure that you download the file to the c:/tftpboot directory; otherwise, the download process does not work.
Step 7 When the SPE firmware is downloaded to your workstation, transfer the file to a Trivial File Transfer Protocol (TFTP) server in your LAN using a terminal emulation software application.
Step 8 When the SPE firmware is downloaded to your workstation, transfer the file to a TFTP server somewhere in your LAN using a terminal emulation software application.
Using an FTP Application
Note The directory path leading to the SPE firmware files on Cisco.com is subject to change without notice. If you cannot access the files using an FTP application, try the Cisco Systems URL http://www.cisco.com/cgi-bin/ibld/all.pl?i=support&c=3.
Step 1 Log in to the Cisco.com FTP server, called cco.cisco.com:
terminal> ftp cco.cisco.com
Connected to cio-sys.cisco.com.
Step 2 Enter your Cisco.com registered username and password (for example, harry and letmein):
Name (cco.cisco.com:harry): harry
331 Password required for harry.

Step 5 Specify a binary image transfer:
Step 6 Copy the SPE firmware files from the universal gateway to your local environment with the get command.
Step 7 Quit your terminal session:
Step 8 Enter the ls -al command to verify that you successfully transferred the files to your local directory:
-r--r--r-- 1 280208 Jul 10 18:08 np-spe-upw-1.0.1.2.bin
Step 9 Transfer these files to a local TFTP or Remote Copy Protocol (RCP) server that your universal gateway or router can access.
Copying the SPE Firmware File from the Local TFTP Server to the SPEs
The procedure for copying the SPE firmware file from your local TFTP server to the Universal Port DFC is a two-step process. First, transfer the SPE firmware to the universal gateway's Flash memory. Then, configure the SPEs to use the upgrade firmware. The upgrade occurs automatically, either as you leave configuration mode, or as specified in the configuration.
These two steps are performed only once. After you copy the SPE firmware file into Flash memory for the first time, you will not have to perform these steps again.
Note Because the SPE firmware is configurable for individual SPEs or ranges of SPEs, the Cisco IOS software automatically copies the SPE firmware to each SPE each time the universal gateway restarts.
To download SPE firmware to Flash memory, follow these steps:
Step 1 Check the image in the universal gateway Flash memory:
[498776 bytes used, 16278440 available, 16777216 total]
16384K bytes of processor board System flash (Read/Write)
Step 2 Enter the copy tftp flash command to download the code file from the TFTP server into the universal gateway Flash memory. You are prompted for the download destination and the remote host name.
Step 3 Enter the show flash command to verify that the file has been copied into the universal gateway Flash memory:

Configuration Tasks
See the following sections for configuration tasks for the Universal Port port service management feature. Each task in the list is identified as either optional or required:
•Configuring Country Code (required)
•Configuring SPEs to Use an Upgraded Firmware File (optional)
•Disabling SPEs (optional)
•Rebooting SPEs (optional)
•Configuring Lines and Ports (optional)
•Verifying SPE Lines and Port Configuration (optional)
•Configuring Universal Port DFC Ports (optional)
•Clearing Ports (optional)
•Configuring SPE Performance Statistics (optional)

Configuring Country Code
To set the Universal Port DFC to be operational for call set up, you must specify the country name. To specify the country name, perform the following task in global configuration mode:
Command
|
Purpose
|
Router(config)# spe country country name
|
Specifies the country to set the DFC parameters (including country code and encoding). If you do not specify a country, the interface uses the default. If the universal gateway is configured with T1 interfaces, the default is usa. If the universal gateway is configured with E1 interfaces, the default is e1-default. Use the no form of this command to set the country code to the default of the domestic country.
Note All sessions in all DFCs in all slots must be in the idle state for this command to run.
|
Configuring SPEs to Use an Upgraded Firmware File
To configure the SPEs to use the upgraded firmware file, use the following steps, beginning in privileged EXEC mode:
| |
Command
|
Purpose
|
Step 1
|
Router# show spe version
|
Displays SPE firmware versions to obtain the On-Flash firmware filename.
|
Step 2
|
Router# config terminal
|
Enters global configuration mode.
|
Step 3
|
Router(config)# spe slot/spe
or
Router(config)# spe slot/spe slot/spe
|
Enters the SPE configuration mode. You can choose to configure a single SPE, or range of SPEs by specifying the first and last SPE in the range.
|
Step 4
|
Router(config-spe)# firmware upgrade {busyout |
download-maintenance | reboot}
|
Specifies the upgrade method.
Three methods of upgrade are available. The busyout keyword waits until all calls are terminated on an SPE before upgrading the SPE to the designated firmware. The download-maintenance keyword upgrades the firmware during the download maintenance time. The reboot keyword requests the universal gateway to upgrade firmware at the next reboot.
|
Step 5
|
Router(config-spe)# firmware location filename
|
Specifies the SPE firmware file in Flash memory to use for the selected SPEs. Allows you to upgrade firmware for SPEs after the new SPE firmware image is copied to your Flash memory.
Enter the no firmware location command to revert back to the default Cisco IOS bundled SPE firmware.
|
Step 6
|
Router(config-spe)# exit
|
Exits SPE configuration mode.
|
Step 7
|
Router# exit
|
Exits global configuration mode.
|
Step 8
|
Router# copy running-config startup-config
|
Saves your changes.
|
Note The copy ios-bundled command is not necessary with Universal Port DFCs. By default, the version of SPE firmware bundled with the Cisco IOS software release transfers to all SPEs not specifically configured for a different SPE firmware file.
Disabling SPEs
To disable specific SPEs in the Universal Port DFC, complete the following tasks starting in global configuration mode:
Command
|
Purpose
|
Router(config)# spe slot/spe
or
Router(config)# spe slot/spe slot/spe
|
Enters SPE configuration mode. You can also configure SPEs specifying the first and last SPE in the range.
|
Router(config-spe)# busyout
|
Gracefully disables an SPE by waiting for all the active services on the specified SPE to terminate.
You can do autodiagnostic tests and firmware upgrades when you put the SPEs in the busiedout state. Active ports on the specified SPE will change the state of the specified range of SPEs to the busyoutpending state. The state changes from busyoutpending to busiedout when all calls end. Use the show spe command to see the state of the range of SPEs.
Use the no form of this command to reenable the SPEs.
|
Router(config-spe)# shutdown
|
Clears active calls on all ports on the SPE. Calls can no longer be placed on the SPE because the SPE state is changed to busiedout.
Use the no form of this command to reenable the ports on the SPE.
|
Rebooting SPEs
To reboot specified SPEs, do the following task in privileged EXEC mode:
Command
|
Purpose
|
Router# clear spe slot/spe
|
Allows manual recovery of a port that is frozen in a suspended state. Reboots SPEs that are in suspended or Bad state. Downloads configured firmware to the specified SPE or range of SPEs and power-on self-test (POST) is run.
Note Depending on the problem, sometimes downloading the SPE firmware might not help recover a bad port or an SPE.
This command can be run regardless of the state of SPEs. All active ports running on the SPE are prematurely terminated, and messages are logged into the appropriate log.
|
Configuring Lines and Ports
To configure the lines and ports to dial in to your network, complete the following steps, beginning in global configuration mode:
| |
Command
|
Purpose
|
Step 1
|
Router(config)# line slot/port slot/port
|
Enters the line configuration mode. Specifies a range of slot and port numbers to configure.
Note The Universal Port DFC slot is defined as a value between 1 and 7. Slot 0 is reserved for the motherboard. Each Universal Port DFC provides 18 SPEs. The SPE value ranges from 0 to 17. Because each SPE has six ports, the Universal Port DFC has a total of 108 ports. The port value ranges from 0 to 107.
For example, to configure 108 ports on slot 3, enter line 3/00 3/107. To configure 324 ports on slots 3-5, enter line 3/00 5/107.
|
Step 2
|
Router(config-line)# transport input all
|
Allows all protocols when connecting to the line.
|
Step 3
|
Router(config-line)# autoselect ppp
|
Enables remote IP users running a PPP application to dial in, bypass the EXEC facility, and connect directly to the network.
|
Step 4
|
Router(config-line)# modem inout
|
Enables incoming and outgoing calls.
|
Step 5
|
Router(config-line)# modem autoconfigure type name
|
Configures the attached modem using the entry for name.
|
Verifying SPE Lines and Port Configuration
To verify your SPE line configuration, do the following steps:
Step 1 Enter the show spe command to display a summary for all the lines and ports:
Step 2 Enter the show line command to display a summary for a single line:
Note If you are having trouble, make sure that you have turned on the protocols for connecting to the lines (transport input all) and that your universal gateway is configured for incoming and outgoing calls (modem inout).
Configuring Universal Port DFC Ports
This section describes how to configure Universal Port DFC ports. You need to be in port configuration mode to configure the Universal Port ports. The port configuration mode allows you to shut down or put individual ports or ranges of ports in busyout mode. To configure Universal Port ports, do the following steps beginning in global configuration mode:
| |
Command
|
Purpose
|
Step 1
|
Router(config)# port slot/port
|
Enters port configuration mode. Configures a single port.
|
Step 2
|
Router(config-port)# port slot/port slot/port
|
Configures a range of ports.
|
Step 3
|
Router(config-port)# busyout
|
(Optional) Gracefully disables a port by waiting for the active services on the specified port to terminate. Use the no form of this command to re-enable the ports.
Maintenance activities, such as testing, can still be performed while the port is in busyout mode.
Note When a port is in busyout mode, the state of the SPE is changed to the consolidated states of all the underlying ports on that SPE.
|
Step 4
|
Router(config-port)# shutdown
|
(Optional) Clears active calls on the port. No more calls can be placed on the port in the shutdown mode. Use the no form of this command to reenable the ports.
Note When a port is in shutdown mode, the state of the SPE is changed to the consolidated states of all the underlying ports on that SPE.
|
Step 5
|
Router(config-port)# exit
|
Exits the port configuration mode.
|
Clearing Ports
The following privileged EXEC mode commands allow you to clear ports on an SPE:
Command
|
Purpose
|
Router# This will clear port 4/01 [confirm] yes
|
Clears port 1 on slot 4 of the Universal Port port.
|
Router# This will clear port 4/00 - 4/107 [confirm] yes
|
Clears all active ports on slot 4 of the Universal Port port.
|
Configuring SPE Performance Statistics
Depending on the configuration, call record is displayed on the console, or the syslog, or on both. The log contains raw data in binary form, which must be viewed using the show commands listed in the "Monitoring and Maintaining SPE Performance Statistics" section. You can configure some aspects of history events by using the following commands in global configuration mode:
Command
|
Purpose
|
Router(config)# spe call-record modem max-userid
|
Requests the universal gateway to generate a modem call record after a call is terminated. To disable this function, use the no form of this command.
|
Router(config)# spe log-event-size number
|
Sets the maximum size of the history event queue log entry for each port. The default is 50 events per port.
|
Clearing Log Events
The following privileged EXEC mode commands allow you to clear some or all of the log events relating to the SPEs:
Command
|
Purpose
|
Router# clear spe log
|
Clears all event entries in the slot history event log.
|
Router# clear spe counters
|
Clears statistical counters for all types of services for the specified SPE, a specified range of SPEs, or all SPEs. If you do not specify the range of SPEs or an SPE, the statistics for all SPEs are cleared.
|
Router# clear port log
|
Clears all event entries in the port level history event log. You cannot remove individual service events from the port log.
|
Troubleshooting Tips
This section provides troubleshooting information for your SPEs regardless of service type mode.
Note SPE ports that pass the diagnostic test are marked as Pass, Fail, and Unkn. Ports that fail the diagnostic test are marked as Bad. These ports cannot be used for call connections. Depending on how many ports are installed, the diagnostic tests may take from 5 to 10 minutes to complete.
•Enter the port modem startup-test command to do diagnostic testing for all modems during the system's initial startup or rebooting process. To disable the test, enter the
no port modem startup-test command.
•Enter the port modem autotest command to perform diagnostic testing for all ports during the system's initial startup or rebooting process. To disable the test, enter the no port modem autotest command.
You may can also configure the following options:
–Enter the port modem autotest minimum ports command to define the minimum number of free ports available for autotest to begin.
–Enter the port modem autotest time hh:mm interval command to enable autotesting time and interval.
–Enter the port modem autotest error threshold command to define the maximum number of errors detected for autotest to begin.
•Enter the show port modem test command to display results of the SPE port startup test and SPE port auto-test.
When an SPE port is tested as Bad, you can do additional testing by conducting a series of internal back-to-back connections and data transfers between two SPE ports. All port test connections occur inside the . For example, if mobile users cannot dial into port 2/5 (which is the sixth port on the Universal Port DFC in the second chassis slot), attempt a back-to-back test with port 2/5 and a known-functioning port such as port 2/6.
•Enter the test port modem back-to-back slot/port slot/port command to do internal back-to-back port tests between two ports sending test packets of the specified size.
Note You might need to enable this command on several different combinations of ports to determine which one is not functioning properly. A pair of operable ports successfully connects and completes transmitting data in both directions. An operable port and an inoperable port do not successfully connect with each other.
A back-to-back test might look like the following example:
Router# test port modem back-to-back 2/10 3/20
Repetitions (of 10-byte packets) [1]:
*Mar 02 12:13:51.743:%PM_MODEM_MAINT-5-B2BCONNECT:Modems (2/10) and (3/20) connected
in back-to-back test:CONNECT33600/V34/LAP
*Mar 02 12:13:52.783:%PM_MODEM_MAINT-5-B2BMODEMS:Modems (3/20) and (2/10) completed
back-to-back test:success/packets = 2/2
Tip You can reboot the port that has problems using the clear spe command.
•Enter the spe recovery {port-action {disable | recover | none} | port-threshold num-failures} command to perform automatic recovery (removal from service and reloading of SPE firmware) of ports on an SPE at any available time.
An SPE port failing to connect for a certain number of consecutive times indicates that a problem exists in a specific part or all of the SPE firmware. Such SPEs have to be recovered by downloading firmware. Any port failing to connect num-failures times is moved to a state based on the port-action value, where you can choose to disable (mark the port as Bad) or recover the port when the SPE is in the idle state and has no active calls. The default for num-failures is 30 consecutive call failures.
Tip The default recovery time is at 3 a.m. You can also schedule a recovery time using the spe download maintenance command.
•Enter the spe download maintenance time hh:mm | stop-time hh:mm | max-spes number | window time-period | expired-window {drop-call | reschedule} command to perform a scheduled recovery of SPEs.
The download maintenance activity starts at the set start time and steps through all SPEs that need recovery and the SPEs that need a firmware upgrade. The download maintenance activity starts maintenance on the maximum number of set SPEs for maintenance. The system waits for the window delay time for all the ports on the SPE to become inactive before moving the SPE to the Idle state. Immediately after the SPE moves to the Idle state, the system starts to download firmware. If the ports are still in use by the end of window delay time, depending on the expired-window setting, connections on the SPE ports are shut down and the firmware is downloaded by choosing the drop-call option, or the firmware download is rescheduled to the next download maintenance time by choosing the reschedule option. This process continues until the number of SPEs under maintenance is below max-spes, or until stop-time (if set), or until all SPEs marked for recovery or upgrade have had their firmware reloaded.

Glossary
BITS—Building Integrated Timing Source.
bps—bits-per-second.
byte—Bits of information.
call or port—A name used to represent the binding of a TDM channel, service, and data queue to support a bidirectional service on the Universal Port module.
Control Processor (CP)—A processor on the module that supports the Universal Port messaging interface.
DFC—Dial Feature Card, the Universal Port modem carrier card (AS54-DFC-108NP) that occupies a slot in the universal gateway.
ECM—Error Correction Mode
ERL—Echo Return Loss. The expected amount of loss through the system that the echo canceller will manage.
EST Queue—An Error / Status / Trace message queue used to communicate out-of-band information between the host and the module.
host—A physical card that the Universal Port module connects to. This can be either the platform, backplane, or a carrier card.
Mb—Megabit. 1,048,576 million bits.
MB—Megabyte. 1,048,576 million bytes.
MIB—Management Information Base.
Port Management Database—A database that consists of Service Processing Element and port level management information for all services.
port, timeslot, or DS0—The atomic element of a TDM stream. It provides a bandwidth of 64,000 bps.
Receive or Rx—Indicates the direction from the TDM stream to the module to the host.
RBS—Robbed Bit Signaling: a form of signaling that "robs" bits from the user's data stream to provide supervisory and signaling information to and from the switch. RBS emulates older analog trunk and line signaling methods by providing a 1:1 mapping of analog supervisory signaling to the signaling bits (A,B,C,D).
RTP/RTCP—Real-Time Control Protocol: provides time-stamp services and allows for the establishment of point to multipoint voice connections.
Service—The algorithm executing on the Universal Port module that implements a particular protocol. Two typical examples of services are a data modem and Voice over IP.
shared memory interface—A communication mechanism where a block of memory can be accessed by multiple processors and that is used to exchange information.
SPE—Service Processing Element. A component of a Universal Port module to which sessions are assigned. An SPE is a logical entity that groups six modems.
Service Processing Unit (SPU)—The processor on the module that runs protocols to process in-band data.
SSRC—Identifies the synchronization source. This identifier is chosen randomly with the intent that no two synchronization sources within the same RTP session will have the same SSRC identifier.
TCF—Training Check Frame. Last step in a series of signals in a fax transmission called a training sequence, designed to let the receiver adjust to telephone line conditions.
TDM—Time division multiplexing. The process whereby a high-bandwidth channel is subdivided into multiple lower-bandwidth channels.
TDM channel—One or more time slots of the HMVIP stream that constitute a single data stream. The TDM channel bandwidth is determined by 64,000 multiplied by the number of time slots in the channel.
TDM stream—An HMVIP serial data stream operating at 8.192 MHz and capable of supporting
8.192 MB throughput.
Transmit or Tx—Indicates the direction from the host to the module to the TDM stream.
Universal Port Module—A voice and data hardware card that supports the Universal Port hardware and software interfaces.
universal service—A port on a Universal Port module that can be switched freely between two or more services without changing the TDM channel.
VoATM—Voice Over ATM. Voice over ATM enables a router to carry voice traffic (for example, telephone calls and faxes) over an ATM network. When sending voice traffic over ATM, the voice traffic is encapsulated using a special AAL5 encapsulation for multiplexed voice.
VoFR—Voice Over Frame Relay. Voice over Frame Relay enables a router to carry voice traffic (for example, telephone calls and faxes) over a Frame Relay network. When sending voice traffic over Frame Relay, the voice traffic is segmented and encapsulated for transit across the Frame Relay network using FRF.12 encapsulation.
VoIP—Voice over IP. The ability to carry normal telephony-style voice over an IP-based internet with POTS-like functionality, reliability, and voice quality.
