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

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

Ethernet over unframed E1 w/SNMP
EOE1A Ethernet over unframed E1 w/SNMP
The EOE1A is a Channel Service Unit for unframed ITU-T G.703 E1 that features a built-in Ethernet bridge. The CSU has a built-in Network Terminating Unit (NTU) and may connect to either 75 Ohm unbalanced, BNC connectors or to 120 Ohm balanced, unframed E1 via twisted pairs and a shielded RJ-45 connector. The EOE1-A Ethernet Bridge uses HDLC encapsulation to transport Ethernet packets across the WAN and supports 10/100 auto-negotiation or manual settings for 10M, 100M, Full or Half Duplex Ethernet. The Ethernet port also supports a standard auto-MDIX feature that will completely eliminate Ethernet cross-over cables or the guessing that is sometimes involved in choosing a cable when connecting to a HUB or a PC. The EOE1-A is very easy to configure by a menu driven serial console interface. SNMP and proprietary MIB add the ability to manage the EOE1-A centrally through third party network management software.
