Virtual Container over Packet Transceivers OC-3 / STM-1, OC-3/12 / STM-1/4

The Small Form-factor Pluggable (SFP) modules convert a data stream from its user SONET/SDH port into circuit-emulated packets for transmission over a Packet Switched Network (PSN). One is capable of OC-3/STM-1 rates (155 Mb/s) while the other adds OC-12/STM-4 signal rates (up to 622 Mb/s). Packets are transmitted via a 1 Gigabit Ethernet (GbE) port on the host device through one or more PSNs (in the case of multiple operators, for example). At the remote end, packets are converted back to TDM traffic for handoff as TDM services.

Virtual Container over Packet Transceiver T3/DS3

The SFP module converts a data stream from its user T3 port into circuit-emulated packets for transmission over a Packet Switched Network (PSN). Packets are transmitted via a 1 Gigabit Ethernet (GbE) port on the host device through one or more PSNs (in the case of multiple operators, for example). At the remote end, packets are converted back to TDM traffic for handoff as TDM services.
