RAD IMX-4T1 6 Mbps Inverse Multiplexer

 FEATURES

  • The IMX-4T1 Inverse Multiplexer enables splitting and transmitting a high speed data channel of up to 5.888 Mbps, over up to four T1 links. IMX-4T1 spans the bandwidth gap between T1 and T3, providing increased bandwidth where services higher than T1 are either not available or are too expensive.
  • IMX-4T1 can be ordered with either 2 or 4 T1 links. For long range applications, a built-in CSU for each of the links is available.
  • Differential delays of up to 64 msec between the T1 lines are tolerated. IMX-4T1 compensates for such delays, and the original stream is reconstructed. The end-to-end delay of the IMX-4T1 is not more than the maximum differential delay between the links.
  • The automatic rate fallback feature ensures that the logical channel remains open even if individual T1 links fail, by automatically dropping to the next lower rate. When failed links are recovered, IMX-4T1 automatically returns to the original rate.
  • IMX-4T1 provides immediate connection to installed applications. The user data port is available with the following sync data interfaces: V.35, RS-530, V.36/RS-449, X.21 or HSSI. The data rate can be any multiple of 1.472 Mbps, up to a total of 5.888 Mbps.
  • An Ethernet Bridge port can be ordered instead of a sync data port interface. The Ethernet bridge port option allows direct connection to LAN and provides self learning and extensive packet filtering. The Ethernet bridge has 10BaseT (UTP) interface, and fully complies with IEEE 802.3.
  • The Ethernet bridge uses an Enhanced Tinygram compression algorithm, enabling it to utilize bandwidth more efficiently and thus reduce the required number of T1 lines.
  • Two user-selectable clock modes are available for the sync type data port:
    - DCE: IMX-4T1 provides both TX and RX clocks to user DTE.
    - External-DCE: IMX-4T1 provides RX clock to user while receiving TX clock from user.

    Note: Ethernet port operates in DCE only

  • System timing options include:
    - Internal clock: the internal oscillator is the source for T1 links.
    - Loopback: the T1 transmit clock is derived from one of the T1 receive clocks.
    - Station clock: the T1 transmit clock is the source for framed/unframed all "1"s or G.703 compatible.
  • Setup, control, status, alarms and diagnostic information are provided via the front panel LCD display or an ASCII terminal/Telnet.
  • Diagnostics capabilities include:
    - Local/remote data port loopback
    - Local/remote T1 links loopback
    - V.52 BERT.

    Diagnostics can be executed via the front panel or ASCII terminal (connected to supervisory port).

    IMX-4T1 also supports the T1 network loopback per AT&T 62411 (in-band code activated), with statistical diagnostic capability according to AT&T PUB 54016.

  • The supervisory port supports dial-in/dial-out for remote out-of-band configuration and monitoring (dial-in), as well as for alarm reporting (dial-out).
  • Compliance is provided for ACCUNET Fractional T45 Service (AT&T), which allows choosing new transmission speeds higher than T1 rates.
