Overview
Flexible Serial Data Extensions over IP Packet or MPLS Networks
The IP•Tube SER DS0 converts serial data connections into IP packets, extending the serial data over very cost effective Ethernet or MPLS based LAN/WAN/MAN wired and wireless networks. Synchronous serial protocols such as: SS7, SDLC or HDLC are encapsulated into IP packets. This facilitates the interconnection of Serial Data over IP between Telecom Switches, Data Terminals, Data Acquisition Systems, WAN Routers and Bridges, SCADA RTUs….
Layer 1
In Layer 1 operating mode every bit is encapsulated into an IP packet. The size and frequency of the IP packets can be set with data rates from 75 bits to 2.048 Megabits per second. Latency minimization is accomplished with FIFO sizing for the low data rate settings. A configured number of incoming packets are buffered in order to compensate for the packet delivery jitter introduced by the Ethernet network. The size of this buffer is configured to accommodate the peak amount of jitter.
SS7 Over IP
SS7 signaling network elements such as local and tandem switches, Mobile Switching Centers, Signal Transfer Points and Home Location Registers that are are efficiently interconnected to remote network elements.
HDLC Over IP
In Layer 2 operating mode HDLC Data frames, such as those used by Wide Area Networking protocols PPP and Frame Relay or proprietary Data Links, are transported within IP packets as HDLC over IP. The Serial to Packet conversion only occurs when HDLC frames are active.
Dual LAN Interfaces
All IP•Tube SER DS0 models ship with dual 10/100 BaseT Ethernet LAN ports. The dual Ethernet interfaces provide for:
• Management interface on LAN port 2 when LAN port 1 is connected to a VPN tunnel
• Protector Option for Redundant Packet Path connections with Constant or Switch Over Criteria
Assured Delivery Protocol
In order to assure high quality communications over links with intermittent or noisy performance, such as Wireless, the IP•Tube SER DS0 employs Engage’s robust Assured Delivery Protocol with the following benefits:• Packet out of sequence detection and re-sequencing
• Duplicate skipping
• Lost packet retransmissions with configured delay
Protector Option
The protector option utilizes the second LAN interface as a redundant path for the interconnection of the IP encapsulated SER DS0 data. The extension of the SER DS0 has a fault tolerant link that is configured to always on, or with switch over criteria.
