Data commands apply to setting up, configuring, and statistical reporting on data connections. For descriptions of the data commands on a FastPAD, refer to the FastPAD User's Guide. Examples of the tasks described in the chapter are:

Setting up a circuit line and a data connection
Configuring data channel redundancy
Using interface control templates
Enabling DFM and data channel utilization
Enabling Embedded EIA operation
Setting up DDS trunks
Configuring idle code suppression on a per-connection basis

The nodes and card sets to which the commands in this chapter apply are:

On an IGX node, the card sets are the

HDM/SDI,
LDM/LDI
CVM/BC-T1, BC-E1, or BC-J1
UVM/UVI-2T1, UVI-2E1, or UVI-2J1

Setting Up a Data Connection

To set up a data connection:

Step 1 If necessary, configure the data channel at each end of the connection. Default configuration parameters exist, so using the following commands are optional. The designation of a data channel has the format slot.port. For example, 6.3 is port 3 on the card in slot 6. The items that need configuring depend on the type of data connection. The configuration commands and their associated parameters are as follows.

	♦ cnfdclk	Specifies the clocking for the data channel
	♦ cnfcldir	Sets the control leads for bidirectional pins 11 and 23 on an EIA/TIA-232 data channel. The default is input
	♦ tstport	Use sixth lead feature to provide test port loopback
	♦ addyred	Enables optional card redundancy. This step requires extra hardware.
	♦ cnfict	Configures an interface control template that determines output lead behavior for data channels. Output leads can be either configured as steady state (on or off) or programmed to follow an input lead. Five types of templates exist for channels in active, conditioned, looped, near, and far states.
	♦ cpyict	Copies interface control template information from one channel to another. This step is optional.

Step 2 Add the connection with the addcon command. The above configuration must have been completed at each end before the connection can be added.

Configuring Data Channel Redundancy

You can configure redundant data channels by installing two identical card sets in adjacent slots and connecting the cards to the customer's line through a Y-cable. Applicable commands are:

Use the addyred command to establish the redundant connection between the two card sets.
Use the delyred command to remove redundancy from a redundant pair.
Use the dspyred command to display Y-cable configurations.
Use the prtyred command to print Y-cable configurations.

Using an Interface Control Template

Data channels have an associated default interface control template for each of the active (normal), conditioned, looped, near and far states. The templates define how the control leads at the data interface are to be configured (asserted, inhibited, follow a local source or follow a remote source). The interface control template can be changed by using the cnfict command. Each template and each control lead must be configured individually. The cpyict (copy interface control panel) can be used to apply (copy) the settings of a template for one data channel to those of a template for another data channel.

Enabling DFM and Data Channel Utilization

DFM (Data Frame Multiplexing) is a feature on the IGX nodes in which repetitive data patterns (such as IDLE codes) are suppressed at the source and regenerated at the remote node. This feature has the effect of approximately doubling the bandwidth of the data channel.

Note DFM operates on connections with maximum rate of 128 Kbps.

The command for changing the DFM enable-status for individual data channels is cnfchdfm. Before you execute this command, make sure the DFM feature has been activated on each applicable node by Customer Service. You can check the DFM configuration for a channel by using the dspchcnf command. When the DFM feature is first activated at a node, it has the following default values:

Percent of channel utilization is 100%
Pattern length is 8 bits
DFM status is enabled.

Enabling Embedded EIA Operation on the LDP or LDM

The EIA feature encodes the status of the CTS or RTS lead as the eighth bit in each data byte. The byte subsequently is processed in accordance with the DFM algorithm, which remains unchanged.

Any DCE and DTE combination at each end is valid. A typical configuration might have the LDP at one end of a connection as DCE (normal clocking) and an LDM at the other end as DTE (looped clocking). RTS is transmitted in encoded form from the remote end to the local end, and CTS is transmitted in the other direction. Other EIA leads use the non-interleaved format.

The EIA feature is allowed for all legal baud rates 19.2 kbps and below and is activated by typing encoding type 7/8E followed by an *Z when adding a connection using the addcon command. Different channels on the same card may be set up with or without the feature, but all ports on the card must be configured at or below 19.2 kbps for EIA to be active. Note that you do not have to enter *Z after 7/8E on the command line because the system automatically enters it.

Setting Up DDS Trunks

DDS Trunks normally operate at 56 Kbps. The IGX nodes can provide a direct interface to a DDS line and provide limited distance access to Data Service Units (DSUs) by using the DDS format over private lines. The LDI4/DDS back card and LDP (Model B) or LDM front card support DDS. Each LDI/DDS supports four DDS trunks in DSU or OCU modes.

Use the cnfdchtp command to configure the DDS port. Specify OCU or DSU for the port type.
Add the connection using the addcon command. When prompted for the rate, enter 2.4 Kbps,
4.8 Kbps, 9.6 Kbps, 19.2 Kbps, or 56 Kbps.

Configuring a Channel to Use Idle Code Suppression

In Release 9.2, the UVM and CVM cards on the IGX support Idle Code Suppression (ICS) for video calls. You can configure the idle code suppression (ICS) feature on an Nx64 super-rate PVC connection (which uses multiple channels) to stop fast packet generation when the connected PBX has terminated a video call. No video traffic will be generated when a video call has terminated. Use the chfdch and dspchcnf commands to enable or disable idle code suppression for the UVM and CDP/CVM cards, and to display the configuration for the cards. All back card types supported by UVM/CVM/CDP support the idle code suppression feature.

Note The UXM/CVM firmware needs to be upgraded for this feature. The CVM model B revision E and above support this feature. The UVMs Model E and above supports this feature. The dspcd screen displays "Front card supports idle code suppression."

The UVM/CVM card firmware detects the idle (on-hook) state of a video call, which uses an nx64K data connection, and suppresses packet transmission during this idle connection. The UVM or CVM at the far end of the connection plays out the idle code during this time. You use the switch software cnfdch and dspchcnf commands to enable/disable and display this feature on a per connection basis. The primary benefit of the ICS feature is the trunk bandwidth savings during the on-hook state of an nx64 connection. This extra bandwidth can be used by other connections.

addcon

Establishes data channel connections between nodes in a network. After you add a connection using the addcon command, the node automatically routes the connection. The node where you execute addcon is the "owner" of the added connections. The concept of ownership is important because you must enter information about automatic rerouting and preferred routing at the node that owns the connection. See the cnfpref and cnfcos commands for more information on automatic rerouting. Before the node adds the connection, the proposed connection appears on the screen with a prompt for you to confirm the addition.

When applied to data connections, the addcon command adds a synchronous data connection to the network. You can add synchronous data connections to any node slot equipped with either an LDM or HDM in an IGX node. Before you add a connection, determine the desired data rate. To find the data rates that individual cards support, refer to the card descriptions in the Cisco IGX 8400 Series Reference manual or the Cisco IGX Reference manual.

When connecting sets of data channels, you do not have to specify the full channel set for the local end of the connection. You have to designate only the first channel in the range. For example, to add connects 27.1-4 at local node alpha to channels 9.1-4 at beta, you can enter "addcon 27.1-4 beta 9.1". If Y-cable redundancy has been specified, you can add data connections at only primary card slots (not at the secondary card slots). See the addyred description for more information. Standard Data Rates tables follow, listing data rates. The following notations appear with some data rates:

♦ *	Must be used with 8/8 or 8/8I coding.
♦ /n	Specifies a partially filled packet type: the /n allows partial packets to be sent and so avoid the delay incurred by waiting to build a full packet
♦ f	Entered after the data rate, an f specifies "fast EIA" (interleaved EIA) for the connection.
♦ t	Indicates "transparent" (CDP or CVM subrate DS0A): if you include the t-option, the IGX node does not check for supervisory or control information.

All of the above connections generate non-timestamped data packets. DFM is not available on interleaved EIA connections.

In "fast EIA" signalling mode, an interleaved byte of EIA signalling information is associated with every byte of data in a packet. This format is appropriate for applications where EIA lead transitions must closely synchronize with user data. Fast EIA can apply to data rates up to 512 Kbps.

When FastPackets are built using the 7/8 coding format, each octet in the FastPacket payload consists of seven user data bits followed by a "1." This "bit-stuffing" allows these FastPackets to be safely carried on trunks which enforce ones density requirements by ensuring that each octet contain at least one "1" (such as IGX trunks configured for ZCS or AMI encoding). The user data may have any format and may contain any pattern, including all "0"s. The single "1" inserted in the final bit position of each octet ensures that no more than seven consecutive "0"s occur in a FastPacket. The 7/8 coding format is the safest mode to use when the data protocol is unknown and certain trunks in the network use ZCS or AMI.

When FastPackets are built using the 8/8 coding format, each octet in the FastPacket payload consists of eight user data bits. The 8/8 coding format is more efficient than the 7/8 format. However, the ones density requirement on trunks must be met by one of the following:

Ensuring that the end-user equipment data protocol can never send more than seven consecutive "0"s.
Ensuring that the connection can never be carried on a trunk which uses ZCS ones density enforcement.

The vast majority of trunks today use intelligent ones density enforcement schemes, such as B8ZS, HDB3, B3ZS, or CMI. All such trunks can safely carry 8/8 data connections with no risk of data corruption. Data connections can be configured to NOT use ZCS trunks by specifying the optional "*Z" routing restriction.

When FastPackets are built using the 8/8I coding format, each octet in the FastPacket payload consists of eight inverted user data bits, i.e., each "0" is changed to a "1" and each "1" is changed to a "0." The bits are re-inverted at the far end of the connection. For such connections, the ones density requirement on trunks must be met by one of the following:

Ensuring that the end-user equipment data protocol can never send more than seven consecutive "1"s.
Ensuring that connection can never be carried on a trunk which uses ZCS ones density enforcement.

As with the 8/8 coding format, 8/8I connections can be safely carried on the vast majority of trunks today. However, the 8/8I format is primarily intended to provide the efficiency of 8/8 coding for any data which is HDLC or SDLC-based. HDLC/SDLC can never send more than six consecutive "1"s, which, when inverted, automatically meets the ones density requirements of every possible trunk format.

If the data protocol requires an acknowledgment and is delay-sensitive avoid routing the connection over a satellite line (*s for avoid). If 8/8 or 8/8I coding is the selected format, avoid trunks with zero code suppression (*z for avoid) because the zero code suppression could corrupt the last bit in the byte.

cnfcheia

Sets the sampling rate for the updating EIA control leads. You can set this rate from 0 (no sampling) to 20 updates per second and defaults to 2 seconds. This rate governs the polling interval and packet generation rate for the EIA leads associated with the channel.

At 20 updates/second, the control leads are polled for changes every 50 msec. Therefore, changes occurring more rapidly than that may not be detected. If there is no change in EIA lead status, no packet is sent. A minimum of one update per second is sent if the maximum update rate chosen is from 1 to 20. If the connection is configured in such a way that an implied isochronous clock is detected, the update rate is always 20 per second in the same direction as that of the clock signal. For 1.544 Mbps data connections, this defaults to 0. This does not affect EIA sampling rates of "fast EIA" or "embedded" EIA leads.

cnfdch

The cnfdch command lets you configure a super-rate data connection that has idle code suppression (ICS) enabled or disabled, before you add a connection. The ICS information in the cnfdch screen is identical to that of dspchcnf.

The idle code suppression feature provides a way to stop fast packet generation on an Nx64 super-rate PVC connection when the connected PBX has terminated a video call and there are no video calls in progress. Traffic on the data network is therefore reduced. Bursty data can then use this un-used bandwidth.

The idle code suppression feature enables the UVM and CVM to detect the on-hook condition of video conferencing calls. During the on-hook phase, FastPacket generation ceases, resulting in more trunk bandwidth becoming available. All connections that use ForeSight can use this bandwidth, resulting in higher information rate.

The cnfdch command is blocked if one or more specified channels is carrying a voice connection (including t-type).

If some of the specified channels do not yet have any connection attached, those channels will be initialized to a data type channel.

The cnfdch command prompts you to enable or disable idle code suppression with the following prompt:

: Enable or Disable Idle Code Suppression (e/d)?[d]:

The cnfdch command is a level 2 access command, which lets you configure a super-rate data connection that has idle code suppression (ICS) enabled or disabled.

The cnfdchl command lets you configure a channel before you add a connection. The configuration remains the same when connections are removed and added again. This configuration will be removed when the associated line is deactivated.

The Idle Code Suppression feature supported in Release 9.2 provides a way to stop fast packet generation on an Nx64 super-rate PVC connection when the connected PBX has terminated a video call. No video traffic will be generated when a video call has terminated.

Because there are multiple channels involved in an Nx64 data connection, the idle code suppression configuration of the first channel in the Nx64 channel will be used for the entire connection bandwidth.

The cnfdch command is available for level 2 users and above; that is, you must have at least privilege level 2 or above to use this command. Use the cnfdch command to configure a channel before you add a connection. The configuration will stay the same even if connections are removed and added again.

Because there are multiple channels involved in an Nx64 data connection, the idle code suppression configuration of the first channel in the Nx64 bundle will be used for the entire connection.

Configuration must be done for each endpoint of a connection. When the state of an ICS connection changes, no network message is sent to the other end. You can choose to configure the other end if ICS is supported on the other end also. To maximize the benefit of the idle code suppression feature, you should enable ICS on both endpoints of the connection.

To interwork with HDM/LDM/SDP/LDP cards, idle code suppression on UVM/CVM/CDP channel will be turned off for any super-rate connection that also terminates on HDM/LDM/SDP/LDP.

All super-rate data connections will have their ICS state set to "disabled" state unless they have been specifically configured with the cnfdch command to be enabled, or through Cisco WAN Manager (or another SNMP manager application).

How Idle Code Suppression Works

When a video call terminates, the PBX generates the appropriate line idle code (for example, 0x7f for mu-law). Per ITU H.221 video coding scheme, no byte will be repeated on one DS0 for more than 80 times. In the case of BONDING protocol, the maximum is 256 (32 msec). The firmware can distinguish a video call and an idle channel carrying idle code. Idle code suppression is not programmable. Any byte that repeats for more than 32 msec in all DS0s in a super-rate connection will be suppressed.

Switch software determines idle code suppression capability on a card based on firmware model and revision number (for example, it considers that the CVM card supports idle code suppression starting with model B revision E firmware).

The idle code suppression feature for the UVM and CVM cards on the IGX detects the idle (on-hook) state of a video call, which uses an nx64k data connection, and suppresses packet transmission during this idle condition. The UVM or CVM at the far end plays out the idle code during this time. You disable or enable and display the status of idle code suppression on a per-connection basis through the switch software CLI cnfdch and dspchcnf commands.

The UVM and CVM card firmware identifies an on-hook or idle condition by detecting repetition of idle codes. These codes can be present in the regular video traffic also (that is, in H.221 or BONDING frames). The code must repeat a certain number of times before it can be concluded that the call is on-hook. It is not necessary to look for specific idle codes. Any byte-code repeating beyond the threshold (about 32 ms) indicates idle channels. The firmware monitors byte repetition on each nx64 connection for which this feature is enabled. On detecting repetition beyond the specified threshold, FastPacket generation for such a connection would cease. This results in the remote side of the connection to under-run. In this condition, it would transmit the previously transmitted byte on each DS0 for the connection. The UVM/CVM continues to monitor DS0s for the connection to detect a change in data received. Any change would indicate an off-hook condition, after which FastPacket transmission would resume.

The idle code suppression feature consists of IGX switch software Release 9.2, and requires UVM model E firmware and CVM/CDP model B revision E firmware. The new UVM/CVM/CDP firmware ensures that idle code suppression can interoperate with UVM/CVM/CDP cards that do not have idle code suppression capability. Such a configuration means that fast packet generation stops in one direction while the other end continues to generate fast packets. This behaves exactly the same as enabling idle code suppression on one side but not on the other side.

All back card types supported by UVM/CVM/CDP support idle code suppression.

Configuring Idle Code Suppression

The standard configuration involves UVM/CVM/CDP cards on both ends of the video connections. An Nx64 super-rate PVC is set up between the two cards. Each video codec is connected through a PBX which is attached to the UVM/CVM/CDP cards.

The idle code suppression feature is available on IGX. When idle code suppression is disabled on a connection (the default), switch software behaves the same as in releases previous to Release 9.2.

UVM/CVM/CDP cards that support idle code suppression can interwork with HDM/LDM/SDP/LDP cards. If the UVM/CVM/CDP channels are configured with idle code suppression enabled, the actual channel will not have idle code suppression enabled if the other end of the connection is not a UVM/CVM/CDP (that is, HDM/LDM/SDP/LDP).

All connection limitations that exist in Release 9.1 remain the same. A t-type connection is not supported. On a VNS controlled network, t-type SVCs are used for video calls. VNS does not support Nx64 super-rate connections.

The idle code suppression feature provides a way to stop fast packet generation on an Nx64 super-rate PVC connection when the connected PBX has terminated a video call. No video traffic will be generated when a video call has terminated. Current UVM/CVM/CDP implementation restricts N to between 1 and 8. This feature is intended to work with video codecs that implement H.221 or BONDING protocol only.

The basic idea is that when a video call terminates, the PBX will generate the appropriate line idle code (for example, 0x7f for mu-law). Per the ITU H.221 video coding scheme, no byte will be repeated on one DS0 for more than 80 times. In the case of BONDING protocol, the maximum is 256 (32 msec). The firmware can distinguish a video call and an idle channel carrying idle code. It is important to understand that the idle code is not programmable. It is a more general approach where any byte that repeats for more than 32 msec in all DS0s in a super-rate connection will be suppressed.

Switch software's job is mainly one of providing interfaces for configuring of channels by enabling/disabling idle code suppression for super-rate data connections. In turn, switch software informs the UVM/CVM/CDP card if idle code suppression should be used on each of the super-rate connections.

No new hardware is needed. All back card types supported by UVM/CVM/CDP support the idle code suppression feature.

Interface with Cisco WAN Manager and other Network Management Systems

The SNMP agent interface on the IGX provides the following operations: Get/Set of MIB information of the desired state of idle code suppression (enabled/disabled).

If a request fails, a General Error is returned to Cisco WAN Manager. An error string is logged in the switch software error table. Cisco WAN Manager can then optionally obtain the error string from switch software. Examples of error messages are "Card in slot does not support Idle Code Suppression" and "E1 CAS and Voice Channels - Not Configured".

Inserting/Removing Cards (Idle Code Suppression Mismatch)

Given an active non-Y-redundant UVM/CVM/CDP card without ICS support, upgrades to a card with ICS are allowed. However, you cannot downgrade a card with ICS capability to a card that does not support ICS (see Table 7-17).

Given a pair of cards in a Y-redundancy configuration, whether any of them is active or not, they must have the same ICS capability (see Table 7-18).

Upgrading and Downgrading the Idle Code Suppression Feature

Given an active non-Y-redundant UVM/CVM/CDP card without idle code suppression support, an upgrade to a card with ICS support is allowed. Downgrading a card with ICS capability to a card without ICS capability is not allowed.

Upgrading the ICS feature to a Y-redundancy pair that does not support the ICS feature is not allowed. The Y-redundancy pair must be deleted first to upgrade the feature. After both cards complete the ICS upgrade, the cards can be added as a Y-redundancy pair.

cnfdchtp

Configures a CDP, CVM, or LDP or LDM DDS port interface type to OCU or DSU. When configuring DDS operations, this command returns an error if executed on a slot with an EIA/TIA-232 back card. It forces a back card slot from EIA/TIA-232 mode to DDS mode if a back card is not installed and there are no connections. Any Y-cable association is deleted in this case. The clocking tracks the DDS port interface type. OCU type interfaces are configured as "looped", and DSU type interfaces are configured as "normal". The default interface is "DSU".

When configuring CDP, CVM, LDP, or LDM operation, this command configures DCE types as "normal" clocking and DTE types as "looped" clocking. The default type is DCE. For T1 lines, DS0A on T1 unassigned signalling is configurable. When a connection is not present, voice channels are converted to data channels.

unassigned signalling

Specifies an optional parameter for T1 lines to indicate DS0A or T1 unassigned signalling. Enter 'd' for DS0A or 't' for T1.

cnfdclk

Configures the clocking for a data channel. In general, the clock configuration may be normal, split, or looped for an SDP or HDM (fewer options for an LDP or LDM). The clock configuration of each channel of a connection determines how the clock will be propagated through the network, and how external equipment should be synchronized.

If clocking is not set correctly, there may be no synchronization, and the connection will operate in a plesiochronous mode. Each data port can be configured independently to act as either DCE or DTE by adjusting the jumper (SDI card) or changing the adapter cable (LDI card) on the data interface card. The effect of the clocking type designated depends on whether each data port is configured as DTE or DCE. The following data clocking configurations are possible with the cnfdclk command:

DCE-Configured Data Port: Normal Clocking

When the data port is configured as DCE, selecting a clocking type of "n" (for normal) results in clocking as illustrated below. The IGX node, acting as DCE, provides both the transmit and receive data clocks to the user equipment.

Figure 7-1: Normal Clocking on a DCE

DCE-Configured Data Port: Split Clocking

When the data port is configured as DCE, selecting a clocking type of "s" (for split) results in clocking as illustrated below. In "split" clocking, TT may be generated independently of RxC. The maximum data rate for split clocking is 112 kbps.

Figure 7-2: Split Clocking on a DCE

DCE-Configured Data Port: Looped Clocking

When the data port is configured as DCE, selecting a clocking type of "l" (for looped) results in clocking as illustrated below. The "Terminal Timing" signal, called TT or XTC, is simply RxC looped back from the user equipment. In this configuration, it is important that the two clocks (RxC and TT) be frequency locked. This clocking configuration is supported for all data rates.

Figure 7-3: Looped Clocking on a DCE

DTE-Configured Data Port: Normal Clocking

When the data port is configured as DTE, selecting a clocking type of "n" (for normal) results in clocking as illustrated below. The IGX, acting as DTE, receives both the transmit and receive data clocks from the user equipment. When the user equipment is not referenced to the network clock, the maximum data rate for this configuration is 112 kbps. The two clocks must be frequency-locked for proper operation.

Figure 7-4: Normal Clocking on a DTE

DTE-Configured Data Port: Split Clocking

When the data port is configured as DTE, selecting a clocking type of "s" (for split) results in the clocking as illustrated below. When the user equipment is not referenced to the network clock, the maximum data rate for this configuration is 112 kbps. The two clocks must be frequency-locked for proper operation.

Figure 7-5: Split Clocking on a DTE

DTE Configured Data Port: Looped Clocking

If you specify clocking type of "l" (looped) when the data port is in DTE mode, the result is the clocking arrangement shown in Figure 7-6 . The RxC clock signal is the TT(XTC) signal looped back to the IGX node by the user equipment. The network supports this clocking configuration for all data rates. The restrictions to the data clocking schemes are:

Except for special cases, isochronous clocking is limited to data rates of 112 Kbps or less. For higher data rates, all clocks must be frequency-locked to the network.
For any port there must be only one isochronous clock in a direction. Any situation where user equipment provides two clock signals that are not locked is subject to slippage.
Slippage may also occur in any situation where there are opposing user clocks for a single direction of data.

cnfict

Sets the interface control template signals. The signals that can be set using cnfict depend on the type of back card used and whether the hardware is configured for DCE or DTE. On an IGX node, the applicable front cards are the LDM, HDM, FRM, CVM (for data), and FTM (for data). Each data channel has a default interface control template for its active, conditioned, and looped near and far states. The cnfict command is used to change a control template. Each interface control lead in each template is individually configured.

When Y-cable redundancy is in effect, the control template configuration for the data channels terminating at the primary slot is also applied to the data channels of the secondary slot. Any configuration information for the secondary slot is ignored. Table 7-25 shows the configurable leads and the equivalence between EIA/TIA-232C, EIA/TIA-232D, EIA/TIA-449, V.35, and X.21 interfaces. The leads are configurable for each type of data interface supported by the IGX node. The entries under the "IGX Name" column indicate the abbreviations to use when specifying input or output leads on the command line. A node treats leads impartially for non-interleaved connections. Any signal received on an EIA pin at one end may be transmitted to any pin at the other end, up to the maximum of 12 EIA leads on any interface type. For interleaved EIA connections, refer to the "Fast EIA" column. The column shows which leads are carried in the interleaved bytes of the data packets. All remaining leads are carried in standard control lead packets.

Note that pins 11 and 23 on an EIA/TIA-232 port are bi-directional, and their default direction is input. See the cnfcldir command for information on changing the direction of these pins. The cpyict command can be used to copy an interface control template from one data channel to another. You can then edit it by using the cnfict command. The dspbob command displays the state of leads at specified intervals.

Table 7-26: cnfict—Parameters

Parameter	Description
port	Specifies the data channel or Frame Relay port whose interface control template is to be configured. Entered as <slot.port>. On an IGX node, the applicable cards are the LDM, HDM, FRM, CVM, and FTM.
template	Specifies which interface control template to configure for the channel and has the format <a/c/l/n/f>. Valid entries are listed below: The only valid template for a Frame Relay port, X.21 or V.35, is the ACTIVE template. Also, all the output leads have steady state values and do not follow local or remote inputs
	Entry	Template	Description
	a	Active	The active control template is in effect while the data channel is active (normal operation) i.e. when the connection is routed and not failed.
	c	Conditioned	The conditioned control template is in effect when conditioning is applied to the data channel. The conditioned template is used when the network detects that it cannot maintain the connection because of card failures or lack of bandwidth (The connection is failed.)
	l	Looped	The looped template is in effect when the data channel is being looped back in either direction. The looped template is used when addloclp or addrmtlp has been used to loop the connection within the network.
	n	Near loopback	The near template is in effect when running a tstport n command or an addextlp n command on a port. The port is configured such that the external near modem is placed in a loopback.
	f	Far loopback	The far template is in effect when running a tstport f command or an addextlp f command on a port. The port is configured such that the external far-end modem is placed in a loopback.
output	Specifies the output lead. Refer to the Configurable Lead information in the command description for abbreviations. Configurable output leads vary with the type of data interface (EIA/TIA-232, V.35, X.21, or EIA/TIA -449).
source	Specifies how the lead is to be configured and has the format <on \| off \|local \| remote> <input> [delay]. Valid source choices follow:
	Source Options
	on	The output lead is asserted.
	off	The output lead is inhibited.
	l	(for local) indicates that the output follows a local lead.
	r	(for remote) indicates that the output follows a remote lead.
	input	Specifies the name of the local or remote input lead that the output lead follows.
	delay	Specifies the time in milliseconds that separates the "off" to "on" lead transitions. Delay is valid only when the output lead is CTS and the input lead is local RTS. "On" to "Off" lead transitions are not subject to this delay.

cpyict

Copies all control template information associated with a given channel: the active template information, the conditioned template information, and the looped template information for near and far ends. Once copied, the control template information may be edited with the cnfict command. See the cnfict command for more information on interface control templates.

On an IGX node, the applicable front cards are the LDM, HDM, FRM, CVM (for data), and FTM (for data).

Parameter	Description
source channel	Specifies the data channel or Frame Relay port whose interface control template information to copy.
designating channel	Specifies the data channel or Frame Relay port that will receive the copied control template information.

delcon

Removes connections from the network. After entry of the channel or range of channels to delete, a prompt requests confirmation of the selection. Connections can be deleted from the node at either end of the connection. Do not delete a connection when the node at the other end of the connection is unreachable. The unreachable node does not recognize the deletion. It is especially important not to delete a connection to an unreachable node and then connect that channel to another node.
