The D12E works with the EG8 to receive and process 32 channels of E1 services. It can be configured with a range of services such as E1 ATM services, E1 IMA services, and E1 CES services.
Table 1 provides the functions and features of the D12E.
| Function and Feature | Description | |
|---|---|---|
| Basic functions | Provides 32 E1 ports, and can transmit/receive 32 fractional E1 services or thirty-two 64 kbit/s CES/IMA services. | |
| Interface types | Supports 120-ohm E1 electrical interface. The electrical interface uses the DB44 connector. | |
| Interface characteristics | Loopback types of the port | Supports inloops and outloops. |
| Auto disabling of port loopback | Supported | |
| CES | Number of supported CES services | 32 |
| Supported emulation mode | CESoPSN SAToP | |
| Timeslot compression | Supports the timeslot compression function. In the case of the CES service in CESoPSN mode, the D12E compresses idle timeslots to improve the bandwidth utilization on the NNI side. | |
| Jitter compensation buffering time | 0.375 ms to 16 ms, in increments of 0.125 ms | |
| Packet loading time | 0.125 ms to 5 ms, in increments of 0.125 ms | |
| IMA | Number of supported IMA groups | 32 |
| Maximum number of E1 links in each IMA group | 16 | |
| Number of V-UNI ports | 8k | |
| Number of V-NNI ports | 4k | |
| Cell concatenation | Mode:
| |
| Maximum number of concatenated cells: 31 | ||
| ATM OAM | Type:
| |
| Quantity: 8k | ||
| Service type | CBR UBR UBR+ rt-VBR nrt-VBR | |
| ATM QoS | Supported | |
| Clock function | Restores four CES adaptive clock recover (ACR) clocks. Clocks that are recovered from services over ports 1 and 9 can be added to the clock priority list. NOTE: Clock recovery over ports 1 to 16 is independent of clock recovery over ports 17 to 32. That is, clocks that are recovered from services over ports 1 to 16 can be transmitted out of ports 1 to 16 and clocks that are recovered from services over ports 17 to 32 can be transmitted out of ports 17 to 32. | |
| Line code of E1 link | HDB3 code | |
| Frame format of E1 link | Unframed format, double-framed format, or E1 CRC-4 multiframe format (default value) | |
