Intelligent 1U4E1PCM30 has 4 E1 ports, 30 channels. All of the 128*128 time slots can be cross-connected flexibly. this function.
Can make 1 E1 of 30 channels of voice data into other 3 E1 ports and merger unsaturated time slots which are from some other E1 ports.
Generally speaking, it makes the single E1 interface card of the county bureau come to 3 E1 interface cards in order to give numbers to sub-branch agencies.
OTS-155B
OTS-155B offers various types of traffic interfaces such as PDH, SDH and Fast Ethernet with flexible network configurations of linear, ring, etc. The OTS-155B is also well suited for implementation in customer premises. OTS-155B has been developed as a part of H-OPTEL SDH family products.
PDH fiber optical multiplexer with STM-1 rate, two optical interfaces, which constitute 1+1 mode. The equipment can transmit 8E1 simultaneously, 1 channel 100M Ethernet and 1 NX64K V.35.
The LCD is on the front panel, with the help of the buttons you can operate the network both local and remote equipment. Another way is to manage by the PC.
The equipment has both external alarm input circuit and external alarm output circuit. Output device is relay.
The power supply can both AC220V and DC-48V, and it is available for AC and DC inputs feeding simultaneously which can work with 1+1 protection.
1 channel hotmail.
Sound and light alarm.
There are two module of FOM8E1, FOM8E1A is sold in domestic, which is called OMT240M. The optical card is stable, and the network is through COM, and the sub-rack is gray.
FOM480 Fiber optical mutiplexer
Flexible configuration meet the need of applications foreign abroad. Though it is 19 inches in width and 1U in height, it is different from other PDH which is manufactured by other companies. All of the unit cards are hot swappable. A big quantity of this type exported. Either appearance or performance has good quality.
The sub rack of FOM480 multiplexer is made of aluminum alloy and 19 inches in width, 1U in height. It provides 7 slots for unit card, which consists of 2 optical card slots, 1 8.448M Ethernet card slot and 4 service unit slots. The 4 slots can be deployed with 4¨ª-V.35 card, video card or V.11/V.24 card. So the preparation is flexible, and this feature makes the product a multi-service transport platform (MSTP)
The LCD on the front panel of FOM480 shows the operation and alarming status of both local and remote equipment. We and connect the equipment with the PC directly to operate the network management.
The SNMP protocol through Ethernet interface provides the first management system. So you can through the web to operate the network, and when you are on holiday you can also operate the network in the hotel. If you are online and enable the management through Internet on web interface.
The optical interface code rate is 155Mbit/s, so the 100Mbit/s Ethernet is as fast as the MODEM.
The power supply can both AC220V and DC-48V, and it is available for AC and DC inputs feeding simultaneously which can work with 1+1 protection.
The optical interfaces works under 1+1 mode and providing smooth switching which costs 0ms when either the optical card is plugged out or the fiber damaged or cut. And there's no error bit or AIS occurred during the switching. This achieves the real non-damage switching, the most advanced and unique technique of FOM480. The test between some manufactures in the Thailand which can past this test is only one or two.
TRX E1-10/100Base-T developed by Hengguang Technologies, employs the clarity E1 transmission channel in accordance with ITU-T G.703 advice and IEEE802.3 standard with independent intellectual property. It is a kind of remote transmission equipment transmitting 10 Base-T data. With an independent structure, TRXE1-10Base-T can transmit 10Base-T data through E1 channels and extend work distance of the interface between two Ethernets through E1 channels such as optical fiber, microwave DDN nets and so on.
It can use the existing communication network structures and interfaces efficiently without impropriating optical fiber core or additional equipment.
