ETRM01 2U 20-slot E1/T1 Cross Rate Converter Rack

The ETRM01 is a 2U 19 (23)" concentrator rack for E1 and T1 Cross Rate Converters in central office installations. There are 20 slots available for hot swappable FTEC cards. An optional SNMP card can be installed into the first slot for configuration and management, leaving 19 slots available for FTEC cards. The SNMP card provides both local control via an RS-232 serial console port and remote IP management using Telnet, web GUI, SNMP protocol. Each E1 card may be linked to a remote E1/T1 PABX or a stand-alone FTEC Unit. The ETRM01 accommodates an optional second hot swappable shared power supply module which may derive power from AC (100-240) or DC (-48V) power sources. On the front panel of FTEC, combinations of BNC and RJ-45 connectors are utilized for E1 and T1 Line interface connections.

Data to Fractional E1

The FRM220-E1/DATA slide in card DSU/CSU is a digital access unit for Unframed or Fractional E1 services. The FRM220-E1/DATA data channel supports user-selectable transmission rates via selected E1 timeslots, which provides integral multiples of 64kbps or 56kbps, up to a maximum 2.048Mbps (unframed), for a line attenuation of up to 43 dB on twisted pair or coax cable. This  provides an approximate operating range up to 2km (using 22AWG). The FRM220-E1/DATA front panel provides status LEDs for monitoring the CSU and DSU conditions for initiating local and remote loopback with integral BERT. The FRM220-E1/DATA features a Data cable adapter for connection to industry standard routers. When the FRM220-E1/DATA card is Placed in the FRM220 rack with SNMP management, in-band management allows viewing the card and remote converter’s status, type, version, link status, data link status and alarms. Both card and remote can be configured to enable or disable the port, reset the port, set the data rate, modify the clock mode and initiate local or far end loop back test.

FRM220A-Eoe1 - Ethernet over E1

The FRM220A-Eoe1 is an Ethernet over E1 bridge and is part of the FRM220 family of interface converters and fibre optic line drivers.

The FRM220A-Eoe-1, when used in pairs, enables users to connect 2 Ethernet networks together over an E1/G.703 link.

The LAN interface on the unit is presented as a single 10/100BaseTX RJ45 connector and the E1/G.703 interface is presented as either a pair of 75 ohm BNC connectors or a 120 ohm RJ45 connector.

The FRM220A-Eoe-1 has the capability to be connected to both unframed 2.048Mbps E1 interfaces as well as fractional n x 64Kbps E1 services.

Configuration can either be locally done via on-board DIP switches, or if remote management is required the FRM220A-Eoe-1 can located within a managed chassis to allow remote Web, Telnet and SNMP management.

When utilised in a managed environment the remote FRM220A-Eoe-1 can be managed over the E1 link by using the 'spare bits' in Timeslot 0 (fractional operation only).

The FRM220A-Eoe1 also features integral test capabilities to aid in any troubleshooting process. This includes an in-built Bit Error Rate Tester and the ability to place various software loops within the system. This enables engineers at either end of the line to test both the FRM220A-Eoe1's and the connected E1 line.

The Ethernet interface supports auto-negotiation and auto MDI/MDIX, allowing plug-and-play connections without any additional configuration. Alternatively the Ethernet interface can have its speed and duplex hardset if necessary.

ICCL-2 RS232, Current Loop Converter

Current loop devices use current on or current off to transmit binary digits. The ICCL converter interfaces RS-232 systems to 20mA or 60mA current loop ports with open circuit voltages up to 30 V. All the units are very easy to implement. Simply connect the appropriate interface cable and select the DCE/DTE type.

IC232IP Async RS232 short haul modem

The IC232IP Asynchronous, Short Haul Modem, overcomes the limited distances of the RS-232 standard by converting DCE/DTE equipment to full duplex 2 twisted pair wire (Category 3 or better). This series of converters works without any external power supply. The ic232IP-SM operates up to 10 Km depending on the wire gauge and data rate.

IC485IP Async RS232 to RS422/RS485, RJ-45 Interface Converter

The IC485IP Interface Converters provide asynchronous conversion between RS-232 interface and RS-485 standard interface. The RS-232 interface connection is via the unit's DB-25 female connector, while the RS-485 side's  connection is via either a five screw terminal block or an RJ-45. The ic485IP converter's circuitry is not electrically isolation between the RS-232 and RS-485 sides. The RS-232 side may operate as DTE or DCE, has provisions for establishing hardware flow control, and has LEDs to indicate data transmission and reception. The RS-485 side may operate in either two wire half duplex or four wire half or full duplex and also has LED's to indicate data transmission and reception.

RS232 Data Interface Converter

The RS232IP family of interface converters allows full bi-directional synchronous conversion between RS-232C (V.24) and V.35, X.21 or RS-449/530 hardware. These converters all work WITHOUT an EXTERNAL POWER SUPPLY. The RS232IP interface converters are designed for synchronous RS-232 operation at data rates up to and including 128kbps. They may also be applied to asynchronous RS-232 using only TD & RD signals, while ignoring TC, RC, and XTC timing signals.  Asynchronous RS-232 requires three times greater data throughput on the synchronous side's V.35, X.21 or RS-449/530 interface. The physical connections for all RS232IP family converters are DB25 female with standard pin out, while a cable adapter is required for V.35, X.21 or RS-449/530 side. All three models may be interchanged as long as the correct V.35, X.21 or RS-449/530 cable is applied.

RS485 Interface Converter

The V35/485-1 Interface Converter provides conversion between V.35 and RS-485 standard interfaces. The V.35 interface connection is via a supplied adapter cable and the unit's DB-25 female connector, while the RS-485 side's connection is via a five screw terminal block. The V35/485-1 converter's circuitry provides a high degree of electrical isolation between the V.35 and RS-485 sides. The V.35 side may operate as DTE or DCE, switch selectable, has provisions for establishing hardware flow control, and has LEDs to indicate data transmission and reception. The RS-485 side may operate in either two wire half duplex or four wire half full duplex.

V.35 Data Interface Converter

The V35IP family of interface converters allows full bi-directional synchronous conversion between V.35 and X.21 or RS-449/530 hardware. These converters all work WITHOUT an EXTERNAL POWER SUPPLY. The V35IP interface converters are designed for synchronous V.35 operation at data rates up to and including 2048kbps. They may also be applied to asynchronous V.35 using only TD & RD signals, while ignoring TC, RC, and XTC timing signals. Asynchronous V.35 requires three times greater data throughput on the synchronous side's X.21 or RS-449/530 interface. The physical connections for all V35IP family converters are DB25 female connectors and V.35 adapter cable. The V.35 side requires the supplied DB25 to MB34 adapter cable to connect directly to V.35 equipment.
