DTE Port Configuration

Configure the protocol, physical layer options, protocol options, and protocol address table for the two DTE ports located on the rear of the FSU by selecting DTE PORT 1 or DTE PORT 2 from the Configuration menu. Figures 6-1illustrates the VT 100 configuration menu for DTE Port 1.

Configure the Network Port before the DTE Ports. Selections made will affect the choices available for the DTE ports.

Chapter 6. DTE Port Configuration

When configuring the DTE ports, select the protocol first. This selection determines which parameters will be available in the other three categories (Physical Layer Options, Protocol Options, and Protocol Address Table). See Figure 6-2for the menu tree leading to the protocol selection. Definitions for each choice follow, categorized by the selected protocol.

In this chapter, the VT 100 selections are listed first followed by the

Front Panel selections (if the names differ).

Chapter 6. DTE Port Configuration

Frame Relay Protocol

The frame relay protocol is a synchronous protocol used to concentrate two different devices into a common frame relay link to the network. While configured for frame relay protocol, the FSU accepts frame relay frames from a router or a FRAD and routes to/from the network port based on the DLCI address. The address can be modified or preserved from the DTE and network side based on the frame relay address table. FECN, BECN, DE, and C/R states are not changed as frames are transferred between the DTE and the network ports. The menu tree in Figure 6-4shows the choices available when the frame relay protocol is selected.

Physical Layer Options

Interface Type (CONN)

Select the connector type for the DTE interface. The choices are V.35 and RS-232.See the appendixPinouts for the connector pin assignments.

Synchronous Bit Rate (RATE)

Select the operating speed of the DTE interface. The selections are 2400, 4800, and 9600 bps and 19.2, 38.4, 56, 64, 112, 128, 168, 192, 224, 256, 280, 320, 384, 448, and 512 kbps.

Speed selections made for the Network Port affect the choices available for the DTE ports.

Synchronous Idle Method (IDLE)

Enable the FSU to transmit flags or all ones. When operating the frame relay protocol, configure this option to transmit flags.

Hardware Flow Control (HDW FLOW CTRL)

When enabled, the FSU varies the transmit clock rate to temporarily limit the transmit data rate to the FSU.

Chapter 6. DTE Port Configuration

Protocol Options

Signaling Type (SIGNAL)

Set the signaling type for the DTE port to match the signaling type of the connected DTE device. Choices are none, FRF LMI, ANSI T1.617-D,andITU-TQ.933-A.If none is chosen, the signaling state for the DTE port is always up.

T392

Set the timeout between polling intervals. This parameter needs to be a few seconds longer than the T391 setting of the attached frame relay device.

N392 and N393

These parameters define the error threshold for the UNI formed by the FSU DTE port and the attached frame relay device. If the error threshold is met, the signaling state status is changed to down, which indicates a service-affectingcondition. This condition is cleared once N393 consecutiveerror-freeevents are received. N392 defines the number of errors required in a given event window, while N393 defines the number of polling events in each window.

For example:

If N392=3 and N393=4, then if three errors occur within any four events the interface is determined inactive.

The status of the connection can be viewed in the Status menu under DTE Port Signaling State. The status will return to active once the threshold is no longer exceeded.

Guidelines for Configuring IP Addr, Subnet Mask, and Mng DLCI

If the attached router or FRAD is used to route SNMP/telnet frames to the FSU, set the Management DLCI to a unique value that identifies the virtual circuit between the router/FRAD and the FSU. The router/FRAD must also be configured to route the FSU IP address to this DLCI. The IP address and subnet mask for the DTE port must also be set.

Chapter 6. DTE Port Configuration

Setting the IP address to 0.0.0.0 and setting the Mng DLCI to a value not used by the attached frame relay device disables this feature.

IP Address (IP ADDR)

Enter the FSU IP address. Each port capable of carrying IP traffic has its own unique IP address. See the previous section, Guidelines for Configuring IP Addr, Subnet Mask, and Mng DLCI, for more information.

IP Subnet Mask

Enter the subnet number assigned to the network formed by the FSU and the other FRAD/routers across the frame relay network. See the section, Guidelines for Configuring IP Addr, IP Subnet Mask, and Mng DLCI, for more information.

Management DLCI (MNG DLCI)

Enter the management data link connection identifier. The Management DLCI is a special DLCI used between the attached DTE device and the FSU to carry SNMP and telnet packets to/ from the FSU on the DTE port. See the section, Guidelines for Configuring IP Addr, Subnet Mask, and Mng DLCI, for more information.

Protocol Address Table

DTE Port DLCI (PRT DLCI)

Enter the DTE port DLCI into the Protocol Address Table, mapping it to the corresponding Network DLCI. If address translation is not required, set to the value of the corresponding network DLCI element.

Network DLCI (NET DLCI)

Enter the network port DLCI into the Protocol Address Table, mapping it to the corresponding DTE Port DLCI. This element should contain DLCI addresses obtained from the service provider.

Edit Next Entry (NEXT key on front panel)

Edit the next entry in the address table.

Add New Entry (ADD key on front panel)

There should be one entry for every virtual circuit on the frame relay

DTE port.

SDLC Protocol

SDLC is a synchronous, bit-oriented,full-duplex,Layer 2 protocol used to connect SDLC devices to a frame relay network. At Layer 2, SNA networks use SDLC between FEPs(front-endprocessors) and cluster controllers. This protocol selection provides Logical Link Control Type 2 (LLC2). LLC2 defines the data link frame header and supports the multiplexing of one or more data links to/from separate service access points (SAPs). Type 2 provides acknowledged,connection-orientedservice. See Figure6-5.

The PU (physical unit) address, LLC2 SSAP, LLC2 DSAP, and outgoing DLCI are used to set up an end-to-endSDLC session for each PU in the network. The PU address elements should match the address of each controller address attached to the port. The DLCI determines the path across the frame relay network and is given by the service provider. The SSAP/DSAP pairs areuser-definedbut should match between two FSUs for each SDLC session.

All PU addresses for a port must be unique, but it is not necessary that they match the PU address at the remote end. The SSAP/DSAP/DLCI is used to make the connection across the frame relay network.
