Page 6: Product Description
The Loop-V 4100 Universal Multiservice Access Platform is a cross-connect device which connects E1 to the OC3/STM-1 network. When used with STM1 and DS3 linear networks the Loop-V 4100 could provide full STM1 access, OC3 access, and OC3Add-drop. The OC3/STM-1 port could be connected to OC3/STM-1 networks or to Loop-V4200-28 with OC3/STM-1 port.
Page 7: Applications
In this application all optical ports have 1+1 protection. The V4100 could have up to three DS3 drops. Any DS0 inside any DS3 or STM1 port could be cross-connected to any other DS0 inside any DS3 or STM1 port. OC3/STM1 OC3/STM1 Loop-V 4100 Protection OC3/STM1 OC3/STM1...

Chapter 1 Product Description 1.3 Specifications The specifications of the Loop-V 4100 are listed below: Time slot interchange Less than 700µs delay One active map, 3 user stored maps Voice channel conversion A- law to µ-law G.711 CAS signaling transparent(A=0 from E1 becomes A=0 to T1, etc.)
Page 11: Installation
Chapter 2 Installation 2 INSTALLATION 2.1 Site Selection The Loop-V 4100 was designed to be used as a stand alone or rack-mounted device. 2.2 Configuration Setting Figure 2-1 below illustrates the Loop-V 4100 Controller Hardware jumper selection. JUM1 Normal ground...
Page 12: Mechanical, Electrical And Cpu Board Installation
2.3.1.2 Rear View The Rear view of Loop-V 4100 is shown in the following figure. There are 17 slots for different plug-in cards. Slot positions on ports A(M), A(S), B(M), B(S), C(M) and C(S) are used to plug in DS3, E3, HD_E1 and HD_T1 cards.
Page 13: Electrical Connections
The Loop-V 4100 is designed to allow for "hot plug-in" or “hot-swapping” of modules. This means that interface cards can be inserted and removed with the main chassis powered up. Onreplacement of a plug-in card, the previous configuration of the port will be used if the replaced card is of the same type.
Page 14: Cpu Connection
Chapter 2 Installation 2.3.3 CPU Connection The Loop-V 4200-28 can support two CPU boards for redundancy. These two boards are placed in the slots, located in the rear of the chassis, marked “CR 1” and “CR 2”. When the system starts, one CPU board will automatically become the primary unit, and the other will become the redundant.
Page 15: Connection
Chapter 2 Installation 2.5 Connection 2.5.1 Connectors The Loop-V 4100 has different connectors for the different ports: OC3/STM1, DS3, E3, HD_E1, HD_T1, Ethernet, and console. OC3/STM-1: SC, ST or FC-PC, BNC DS3: Ethernet: RJ45 Console: HD_E1 SCSI 68 HD_T1 SCSI 68 2.1.1...

Page 17: Operation
Chapter 3 Operation 3 OPERATION This chapter describes the configuration options and operational functions. Refer to Chapter 5: Terminal Operation for detailed operational procedures of the main unit. Each module also has operational descriptions in their respective manuals. 3.1 Quick Start This quick start section is provided to give a brief overview so operation can begin immediately.
Page 18: Date
3.5.3 Master Clock The Loop-V 4100 has a system clock Phase Lock Loop (PLL), which may be phase locked to the internal clock, an external clock, or the OC3/STM1 and High Density E1 card’s clock inputs. The external clock follows ITU G.703 specifications, which is either a 2.048 MHz or a 1.544 MHz AMI signal (external clock frequency specified on order).
Page 19: Logon, Logoff And Password
3.7 Time Slot Interchange (Digital Access Cross-Connect) An important function of the Loop-V 4100 is Time Slot Interchange (TSI), also known as Digital Access Cross-connect System (DACS), where each DS0 time slot of any line can be assigned to any DS0 time slot of any line including itself.
Page 20 Original time slot order The Loop-V 4100 has four maps, each of which can be modified at any time. However, the "working map" needs to be selected through a command, and then that map will be the current, active map. When the "Store"...
Page 21: Alarms And Reports
3.8 Alarms and Reports For the HD_E1 plug-in card, the Loop-V 4100 has many types of alarms, as listed in Table 3-3 below. The Loop-V 4100 also has an alarm queue which records the latest 200 alarms with a time stamp. Alarm history and alarm status registers, which are used to track the alarm count, are also available.
Page 22: Led Operation
Chapter 3 Operation 3.9 LED Operation The following table lists each LED and its color and indications. Each plug-in module has a rear panel LED, which matches the corresponding front panel LED. The rear panel LEDs are listed in the individual module’s User’s Manual.
Page 23: Snmp Connection
Before SNMP is enabled, make sure the IP address for the Loop-V 4100 is configured correctly and the communication parameters match the Terminal server port. Once the SNMP agent is activated, the ping command can be used to verify the status of the Loop-V 4100. The command is as folows: $ ping 192.1.100.45...
Page 24: Verifying Loop-V 4100 Operations
Especially during initial installation, excessive errors may be due to (a) incorrect configuration of either LOOP-V 4100 or of the equipment at the other end of the line, or (b) due to faulty line installation, which results in excessive noise, cross talk, or impedance mismatch. Especially in electrically noisy environments, such as central offices, the use of shielded cables is mandatory.
Page 25: Loopback Block
Chapter 3 Operation 3.11.3 Loopback Block Figure 3-2, below, illustrates Loop-V 4100 loopbacks. Explanations of these loopbacks follow in the text below the diagram. OC3/STM1 Note: All loopback numbers on this diagram correspond directly to the numbered labels in HD_E1/T1 the list below.
Page 26 Chapter 3 Operation 13. E3 Payload Loopback: Takes all traffic except framing. 14. E3 Local Loopback: Takes all traffic from the back-plane and returns it to the back-plane. 15. E3 (Multiplex 16E1) Line Loopback: Takes traffic from the E3 framer (including E1/T1 framing) and returns it to the E3 framer.
