ASMi-52 Ver. 2.5 Configuring the Physical Ports 4-35
• Transmit signal mask (DS U mode) – length of a cable in feet between the
ASMi-52 T1 port connector and the network access point:
0 feet – 0 to 133 feet
133 feet – 133 to 266 feet
266 feet - 266 to 399 feet
399 feet – 399 to 533 feet
533 feet – 533 to 655 feet
• Transmit signal mask (CSU mode) – re lative T1 output transmit level:
7.5 dB – attenuation of 7.5 dB relative to the nominal transmit level
15 dB – attenuation of 15 dB relative to the nominal transmit level
22.5 dB – attenuation of 22.5 dB relative to the nominal transmit level
• Fbit configuration – F bit transmission mode:
Transparent – F bits are sampled at TSER
Internally Source – F bits are sourced internally.
•
Configuration of the sync mode, idle mode, timeslot assignment and matching of T1
setting of the local and remote units (Unit Identical Set) is identical of that of the E1
interface. Refer to Configuring the E1 Interface section above.
To access the T1 Configuration menu:
1. From the Configuration menu, select T1 Configuration.
The T1 Configuration menu appears.
2. From the T1 Configuration menu, select T1 local port for the local port
configuration or select T1 remote port for the remote port configuration.
The T1 Local/Remote Configuration menu appears (see Figure 4-37).
