Ethernet Configuration:

Select the required Ethernet Configuration for 2+0 or 4+0 Link Types. (PTP 820 and PTP 850 Only)

Single Ethernet (MC-ABC) requires the following:

one Ethernet cable per ODU (PTP 820C, PTP 820C HP or PTP 850C) or per IDU (PTP 820G)

one MC-ABC key per Tx

Note that Single Ethernet (MC-ABC) restricts the capacity to a single Ethernet connection. (1 Gbps for GbE, 2.5 Gbps for 2.5 GbE or 10 Gbps for 10 GbE)

Multiple Ethernet (with or without LAG) requires the following:

two Ethernet cables per ODU (PTP 820C or PTP 850C) or IDU (PTP 820G)

no additional keys to implement LAG

Multiple Ethernet (with LAG) requires internal PTP 820 LAG.

Multiple Ethernet (without LAG) requires link aggregation in the connected external switches.

L1 Link Bonding (PTP 850C Only) - for 4+0 configurations using only one data drop cable per end with short interconnect cables between the two radios

RFU MC-ABC (PTP 820A Only) - for RFU based MC-ABC operation. Cabling and MC-ABC activation key is similar to Single Ethernet (MC-ABC)

TCC MC-ABC (PTP 820A Only) - for TCC based MC-ABC operation. Cabling and MC-ABC activation key is similar to Single Ethernet (MC-ABC)

RFU MC-ABC with L1 Link Bonding (PTP 820A Only) - For 4+0 configurations, RFU based MC-ABC requires L1 Link Bonding.

Product Configuration (unlicensed bands)¶

Select the product parameters. The fields that are displayed in the “Product Configuration” box will change depending on the type of equipment selected. For example, when a PTP 450i is selected the Color Code field is displayed.

_images/ptp_unlicensed_product_configuration.png — PTP Product Configuration (unlicensed bands)¶

note

Some parameters are required when configuring the product but are currently not used in the LINKPlanner calculations, they will be used in future releases. These items are identified as “(information only)” in the descriptions below.

Product Configuration Parameters

Bandwidth: Select the channel bandwidth.

E1/T1: (PTP 670 and PTP 700 only). If the link is to carry telecoms traffic, select the number of E1 or T1 links required. For more information, see Optimizing E1 or T1 Latency.

Optimization: (PTP 670 and PTP 700 only). Select the optimization for the link, either for IP Traffic or TDM Traffic. If TDM is enabled, the link is optimized automatically for TDM traffic/latency.

Sync: (PTP 670 and PTP 700 only). Defaults to Disabled. TDD Synchronization will be added in a future release

Symmetry: (PTP 670 and PTP 700 only). Select the link operation (Adaptive, Symmetric, 2:1, 3:1 or 5:1 - options are dependent on Product and other configuration settings).

Dual Payload: (PTP 670 and PTP 700 only). Allow dual-payload modulation modes for better throughput.

Highest Mod Mode: (PTP 670 and PTP 700 only). Select the highest modulation mode for the Ethernet traffic to limit the maximum throughput rate, default is 256 QAM 0.81 (no limit). Dual or Single will be automatically selected depending on the setting for Dual Payload.

Maximum Mod Mode: (ePMP, PTP Mode or PTP 450 family only). Select the highest modulation mode for the Ethernet traffic to limit the maximum throughput rate, default for ePMP 11n is MCS15 and 11ac is MCS 9 (256QAM 0.83 Dual).

Minimum Mod Mode: (PTP 450 family only) Select the lowest modulation mode for the traffic.

Lowest Ethernet Mode (PTP 670 and PTP 700 only). Select the lowest modulation mode for the Ethernet traffic to achieve the required throughput rate, default is BPSK 0.63 Single.

Lowest Telecoms Mode (PTP 670 and PTP 700 only). When a link is configured for E1 or T1 telecoms traffic, select the lowest modulation mode to achieve the required latency. For more information, see Optimizing E1 or T1 Latency.

Color Code: (PTP 450 and 450i only). Select the Color Code for the link (information only).

Frame Period: (PTP 450 and 450i only). Select the Frame Period.

Downlink Data: (PTP 450 and 450i only). Set the proportion of the link to be used for throughput from the Master to the Slave.

DL/UL Ratio: (ePMP only). Select the required DL/UL Ratio, where DL is the proportion of the link to be used for throughput from the Master to the Slave.

Master: Select which site is the master.

Gb Ethernet Port: (ePMP 1000 only). Select whether each end of the link requires equipment with a GbE port instead of an FE port (the FE port will limit the maximum throughput if selected at either end of the link). Select Gb Ethernet Port at the Master if the link has to be synchronized.
