| Object | Parameter | Description |
| <e1CRC4Status> | : disable | enable | Enables the CRC-4 cyclic redundancy check feature. When enabled, the E1 Access Module generates and monitors for the CRC algorithm carried on bit 1 of timeslot 0 of an E1 frame. |
| <e1LineCode> | : ami | hdb3 | Selects either AMI or HDB3 line code.
- ami indicates that HDB3 suppression is disabled. When AMI is selected, you must ensure that the Data Terminal Equipment is generating at lease one 1 in every four bits.
- hdb3 (High Density Bipolar 3), a ITU-TSS-recommended coding method which limits the maximum number of consecutive zeros to three.
|
| <e1TS16Connection> | : toCAS | idle | bypass | toDataPort1| toDataPort2 | Specifies the signaling system to be used in time slot 16.
- toCAS supports G.704 channel associated signaling. In this method, a multiframe structure of 16 consecutive frames numbered 0 through 15 is used. In each frame, time slot 16 allocates four bits to two channels in the following pattern: Frame 0 = multiframe alignment; Frame 1 = ABCD of Ch 1 and ABCD of Ch 16; frame 2 = ABCD of Ch 2 and ABCD of Ch 17; etc., up to frame 15.
|
| <idleCode> | : INTEGER (0..255) | Sets the idle code for the DS0 channels. Values range from 0 to 255. Specify the profile number (1 or 2). |
| <t1BuildOut> | : lessThan110feet | lessThan220feet | lessThan330feet | lessThan440feet | externalLBO | greaterThan665feet| lessThan550feet | lessThan660feet | Specifies cable length attached to the line. Specify the profile number (1 or 2). |
| <t1FrameFormat> | : superFrame(D4) | extendedSuperFrame(ESF) | Sets the profile for either superframe (D4) or extended superframe (ESF). Superframe consists of 12 frames and extended superframe consists of 24 frames. |
| <t1LineCode> | : ami | b8zs | Sets either AMI or B8ZS zero suppression. AMI disables B8ZS suppression; however, a bit density requirement is created which can be satisfied by assuring that the DTE is generating at least one 1 in every byte. Voice is not affected as PCM code does not allow bytes without a 1. |
| <t1LoopbackStatus> | : disable | enable | Used to enable T1 network-invoked loopback tests. When enabled, the T1 Access Module recognizes and responds to network-invoked loopback commands. When disabled, the T1 Access Module will not respond to network-invoked loopback commands. |
