IP•Tube CEP DRV

The IP•Tube CEP DRV converts TDM or 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....

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 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.

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.

All IP•Tube CEP DS0 models ship with dual 10/100/1000 BaseT Ethernet LAN ports and another pair of Dual SFP LAN ports. The choice of 4 different 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

• Protector Option for Redundant Packet Path connections with Constant or Switch Over Criteria

IP•Tube CEPs isolate management and data plane functionality with the use of two separate processor modules. Management processor access is limited to SSH or SNMPv3 encrypted sessions that employ AES256 bit keys and sophisticated NIST passwords. These sessions may be established after authentication via TACACS+ or Radius.
The independent Linux based management plane of the IP•Tube CEP ensures Critical Infrastructure Data is isolated from management network access. The Management Module uses internal serial ports to connect to the Data Plane processor.

Administration and User Logs are available with Syslog.

CEP management security features include:

• Administrative policies for adding, removing, disabling and renaming authorized users; limiting user access to assigned commands; and enabling only desired port numbers.

• User authentication directly or in conjunction with TACACS+ or RADIUS servers including RSA SecureID support for two factor trusted compliance.

• An SSH command interface encrypting management traffic with powerful 256 bit symmetric keys and NIST based passwords.

• Support of the SNMPv3 protocol for secure connectivity to SNMP element managers.

• In addition, administrative accounting data can be reported to syslog servers with accurate timestamps provided by an NTP source.

The protector option utilizes the second LAN interface as a redundant path for the interconnection of the IP encapsulated CEP DS0 data. The extension of the CEP DS0 has a fault tolerant link that is configured to always on, or with switch over criteria.

The IP•Tube DLT1-MUX maps DSOs from a central site to as many as 24 remote locations via an IP/Ethernet connection. Get maximum use of expensive DS1 interfaces on PBX, Channel equipment and datacom gear. Also provides Virtual DACS Over IP capability. Mesh DS0s one-to-many or many-to-many.
