ONtel Interface Cards

1. QE1B: 4-channel E1 Interface Module:

Connector type: BNC
Impedance: 75Ω±5%
There are E1 (2.048 Mbps) transmission module which provides 4-channel to transmit transparently. The E1 interfaces meet the ITU-T (G.703) and ANSI standards. Each can be configured as E1 by management interface. Meanwhile, the parameter settings, such as line code (HDB3/AMI), are field selectable. These functions can be provisioned via system Console, LCD, Web Server or NMS, when an E1 channel is being provisioned the other channels should not fail during the process The E1 interfaces are individually terminated.

2. 8E1B: 8-channel E1 Interface Module:

Connector type: RJ-48 working with RJ-48 to BNC converting cable
Impedance: 75Ω±5%
There are E1 (2.048 Mbps) transmission module which provides 8-channel to transmit transparently. The E1 interfaces meet the ITU-T (G.703) and ANSI standards. Each can be configured as E1 by management interface. Meanwhile, the parameter settings, such as line code (HDB3/AMI), are field selectable. These functions can be provisioned via system Console, LCD, Web Server or NMS, when an E1 channel is being provisioned the other channels should not fail during the process The E1 interfaces are individually terminated.

3. ET3: 1 -channel E3/DS3 Interface Module:

Connector type: BNC
Impedance: 75Ω±5%
There is E3/DS3(34.368/44.736 Mbps) transmission module which provides 1 -channel to transmit transparently. The E3/DS3 interfaces meet the ITU-T (G.703) and ANSI standards. Each can be configured as E3/DS3 by management interface. Meanwhile, the parameter settings, such as line code (HDB3/B3ZS), are field selectable. These functions can be provisioned via system Console, LCD, Web Server or NMS, when an E3/DS3 channel is being provisioned the other channels should not fail during the process The E3/DS3 interfaces are individually terminated.

4. QSW: 4-port 10/100M Ethernet Interface Module:

Connector Type: RJ-45

QSW provides up to 4 channels of 10/100M Ethernet transmission module. The user can assign the bandwidth in high-speed optical signal for Ethernet data communicating between two ends by the practical needs. The basic incremental unit of the bandwidth is one standard C-12 (about 2.176 Mbps).

5. QV35: 4-channel V.35 Interface Module:

Connector Type: DB-44

QV35 provides up to 4 channels of Nx64Kbps (N=1 to 32) transmission module. The V.35 interface meets ITU-T V.35 standard. User can assign the bandwidth and clock source by management interface. The DTR/RDL/LLB signals can be ignored because of some V.35 DTE does not provide these signals currently.

6. GBE: 4-port 10/100/1000M Ethernet Interface Module

Connector Type: RJ-45, SFP

GBE provides up to 4 channels of 10/100/1000M Ethernet transmission module. Users can choose Electrical or Optical type service. The user can assign the bandwidth in high-speed optical signal for Ethernet data communicating between two ends by the practical needs. The basic incremental unit of the bandwidth is one standard VC-3 (about 48.384 Mbps).GbE card has rich L2 Switch functions like 802.1p QoS, 4096 VLAN table, 8K MAC address, Traffic rate limit control, Loopback test, and something like Media converter function : Link Fault Pass Through Alarm (in the case of Point to point mode).
