The Loop-V4200-9 is a versatile 9-port device.Depending on the plug-in cards selected, this unit can be configured
- as a CSU/DSU with drop and insert and voice capabilities
- as a 4 E1 to 5 T1 converter or fractions of them
- as a digital cross-connect system (DACS)
- as sets of ICSU combined in one box
- as a channel bank.
As a CSU/DSU, data from the V.35 or X.21 port can occupy any fraction of an E1 or T1 port. As an E1 to T1 converter, A to µ law coding and signaling conversions are correctly handled. For both E1 and T1 ports, continuous error checking,performance polling, and in-service diagnostics are provided. In any of the above combinations,full time slot interchange (TSI) among the ports are possible, making the Loop-V4200-9 a small DACS (digital access cross-connect system).The ports can further be used in pairs as ICSUs (intelligent CSU) at a lower cost and smaller space than individual ICSUs. The Loop-V4200 can also be configured as a channel bank.
The Loop-V4200-9 supports local control and diagnostics by using a 2-line, 40-character LCD display and keypads on the front panel, or by using a VT-100 terminal connected to the console port. The Loop-V4200-9 also supports Ethernet, Telnet, and SNMP so it can be controlled and diagnosed from remote locations. The Loop-V4200-9 supports in-band management, where management data is carried over the same channel as user data.
In addition to the LCD display, 12 multicolor LEDs provide status indications for power, test conditions, and alarms for each of the 9 ports.The internal firmware is stored in flash memory sothat the future software upgrades can be downloaded.
