Figure 54 ENET Port Setup The following table describes the labels in this screen. Table 18 ENET Port Setup LABEL DESCRIPTION. When you don’t use auto-negotiation, you must make sure that the settings of the peer Ethernet port are the same in order to connect. Select Auto (auto-negotiation) to have the IES-1248-51V automatically determine the type of connection that the Ethernet port has. It also covers how to configure virtual channels and virtual channel profiles. 16.1 ADSL Standards Overview These are the ADSL standards and rates that the IES-1248-51V supports at the time of writing.

You can configure all of the ADSL ports with the same profile, thus removing the need to configure the ADSL ports one-by-one. You can also change an individual ADSL port by assigning it a different profile. For example, you could set up different profiles for different kinds of accounts (for example, economy, standard and premium). For example, if you configure a profile with a maximum downstream rate of 25000 Kbps, and apply it to a port set to use G.dmt, the IES-1248-51V automatically uses a maximum downstream rate of 8160 Kbps. Table 20 xDSL Port Setup LABEL DESCRIPTION VC Setup Click VC Setup to open the VC Setup screen where you can configure VC settings for the DSL ports (see Section 16.9 on page 129). The port profile settings are configured in the xDSL Profiles Setup screens (see Chapter 17 on page 139). Figure 57 xDSL Port Setting The following table describes the labels in this screen. Table 21 xDSL Port Setting LABEL DESCRIPTION. Use the Port Profile screen to configure port profiles (see Chapter 17 on page. Set the impulse noise protection minimum to have a buffer to protect the ADSL physical layer connection against impulse noise. Masking a carrier tone disables the use of that tone on the ADSL port. Do this to have the system not use an ADSL line’s tones that are known to have a high noise level. You can define up to eight channels on each DSL port and use them for different services or levels of service. You set the PVID that is assigned to untagged frames received on each channel. VC-based multiplexing may be dominant in environments where dynamic creation of large numbers of ATM VCs is fast and economical. 16.8.4 Virtual Channel Profile Virtual channel profiles allow you to configure the virtual channels efficiently. You can configure all of the virtual channels with the same profile, thus removing the need to configure the virtual channels one-by-one.

Table 22 VC Setup LABEL DESCRIPTION xDSL Port Setup Click xDSL Port Setup to go to the screen where you can configure DSL port settings (see Section 16.7 on page 121). Click a PVC’s index number to use the top of the screen to edit the PVC. Note: At the time of writing, you cannot edit the VPI and VCI. If you want to change them, add a new PVC with the desired settings. Click Cancel to only remove the one you selected. The IES-1248-51V uses this PVC channel internally. This PVC is not needed on the subscriber’s device. This PVC cannot overlap with any existing PVC’s on this port. Note: The member PVCs must be created on the subscriber’s device. Then, click a PPVC’s member number to open the PPVC Setup Members screen. Then you can assign them to one or more individual ports. For background information about many of these settings, Chapter 16 on page 119. Table 26 Port Profile LABEL DESCRIPTION VC Profile Click VC Profile to open the VC Profile screen where you can configure virtual channel profiles (see Section 17.5 on page 146). Min SNR Type the minimum upstream signal to noise margin (0-31 dB). Configure the minimum upstream signal to noise margin to be less than or equal to the maximum upstream signal to noise margin. When the channel’s signal to noise margin goes below this number, the device shifts to a lower transfer rate. Configure the downstream down shift signal to noise margin to be less than or equal to the target downstream signal to noise margin and greater than or equal to the minimum downstream signal to noise margin. Connections that use the Variable Bit Rate (VBR) traffic class can be grouped into real time (rt-VBR) or non-real time (nrt-VBR) connections. The rt-VBR (real-time Variable Bit Rate) type is used with bursty connections that require closely controlled delay and delay variation. The following figure illustrates the relationship between PCR, SCR and MBS. Figure 65 PCR, SCR and MBS in Traffic Shaping 17.3.2.

4 Cell Delay Variation Tolerance (CDVT) Cell Delay Variation Tolerance (CDVT) is the accepted tolerance of the difference. Time C is calculated based on the CDVT or BT. Figure 66 TAT, CDVT and BT in Traffic Shaping 17.4 Upstream Policing Upstream policing is an agreement between the carrier and the subscriber to regulate the average rate and fluctuations of data transmission coming from the. Figure 67 VC Profile The following table describes the labels in this screen. Table 27 VC Profile LABEL DESCRIPTION xDSL Profile. SCR applies with the vbr traffic class. Burst Tolerance (BT) is the maximum number of cells that the port is guaranteed to handle without any discards. The IES-1248-51V sends an alarm trap and generates a syslog entry when the thresholds of the alarm profile are exceeded.Table 28 Alarm Profile LABEL DESCRIPTION xDSL Profile Click xDSL Profile to open the Port Profile screen (see Section 17.1 on page 139). Use the Port Profile screen to configure profiles of ADSL port settings (such as the transfer rate, interleave delay and signal to noise ratio settings). If a fast mode (bps) connection’s downstream transmission rate decreases by more than this number, then a trap is sent. Interleave Rate Specify a rate in kilobits per second (kbps). Information obtained prior to training to steady state transition will not be valid or will be old information. Table 29 xDSL Line Rate Info LABEL DESCRIPTION Line Performance Click Line Performance to display an ADSL port’s line performance counters (see Section 18.3 on page 155).

Figure 76 VLAN Port Setting The following table describes the labels in this screen. Copy port Do the following to copy settings from one port to another port or ports. Paste 1. Select the number of the port from which you want to copy settings. Multicast delivers IP packets to just a group of hosts on the network. The IES-1248-51V discards multicast traffic destined for multicast groups that it does not know. IGMP snooping generates no additional network traffic, allowing you to significantly reduce multicast traffic passing through your device.

The IES-1248-51V manages all Join and Leave requests from Hosts 1, 2, and 3 downstream. When the last leave request is received, the IES-1248-51V sends a Leave request upstream to the multicast server to discontinue the traffic. By managing multicast queries in this manner, the IES-1248-51V can present itself as a single recipient to the multicast server.
