Optical Ethernet-Private Line (OE-PL) service using 2x1000 SX/LX OPE circuit packs

OPTera Metro 3500 allows you to provision 2xGigE circuit packs in a point-to-point configuration using only SONET interfaces. You first use the ED-SYS TL1 command to specify 2xGigE point-to-point mode for each shelf involved in the configuration. When a 2xGigE circuit pack is provisioned on the shelf (either manually or by installing the circuit pack in a valid and unprovisioned slot), the circuit pack is automatically configured with the data parameters required to enable point-to-point mode. The point-to-point configuration is established by provisioning a Resilient Packet Ring (RPR) cross-connect between the two circuit packs in point-to-point mode across a ring (UPSR or BLSR). You can provision the RPR cross-connect through TL1 or through Site Manager.

The following lists the data parameters of a 2xGigE circuit pack that are auto-provisioned when point-to-point mode is enabled:

•The CPU port of the circuit pack is set to Optical Ethernet layer 2 (OE/L2) mode, configured with a default gateway address of 0.0.0.0, and configured with an IP address of 10.a.b.c., where a.b.c. are the three least significant bytes of the CPU port media access control (MAC) address

•LAN port 1 is set to OE/L2 mode and configured with an IP address of 10.a.b.c+1, where a.b.c. are the three least significant bytes of the CPU port MAC address

•LAN port 1 is configured as a transparent user-to-network interface (UNI) port with a transparent domain identifier (TDI) of 100

•TDI 100 on LAN port 1 is enabled and set to a connectivity type of point-to-point

•LAN port 1 is enabled

•Token bucket is disabled on LAN port 1. Flow control is therefore based on WAN bandwidth. See the OPTera Packet Edge System Planning Guide (NTN465YG) for more information.

•The IEEE 802.1p priority mapping for TDI 100 on LAN port 1 is disabled, that is, set to 0:0:0:0:0:0:0:0

Note 1: All other data parameters are unchanged from their default values. In particular, auto-negotiation is enabled, pause frames are enabled, and LAN port 2 is disabled. Refer to the OPTera Packet Edge System User Guide (NTN465YG) for a list of default settings.

Note 2: A 2xGigE circuit pack auto-provisioned for point-to-point mode operates in the same way as any other 2xGigE circuit pack. For example, you can change any data parameter of the circuit pack using the existing
