4-16 T ERMINAL O PERATION
NETWORK. Timing is derived from the network recovered clock (most applications
use this selection).
STATION. Timing is derived from a bipolar or TTL-compatible clock supplied to
the unit via the rear panel STA CLK connection. When this mode is selected, the
timing rate must also be set from Station Timing.
Station Timing
Selects the input timing and only appears when Station is selected from the
T1-NET Timing menu. The choices are N
×
56K, N
×
64K, and 1.544 MHz. A
number appears to the right of this field when N
×
56K or N
×
64 K is selected to
indicate the rate multiplier. Enter a value from 1 through 24.
Remote Comm Channel
This field selects a communication link to the far-end unit. If 0 is selected,
communication is established over the ESF facility data link (valid only when the
network interface is configured for ESF framing and the FDL has end to end
integrity). For example, the entire T1 bandwidth is available to the user with no
intervening multiplexors in the signal path that block the FDL.
As an alternative, the communication link may be assigned to an unused idle
channel. This option may be used when the network is operating in D4 or ESF
modes.
When the remote communication is programmed to operate over a spare network
channel, the following test conditions interrupt access to the far-end unit.
✦ A remote network LLB or PLB is initiated.
✦ A local network LLB is initiated.
When the remote communication is programmed to operate over the facility data
link (FDL), the following test conditions interrupt access to the far-end unit.
✦ A remote network LLB is initiated.
✦ A local LLB is activated on the near end.
T1-DTE Framing
Selects the framing for the DTE side of the element. The choices are ESF and D4.
T1-DTE Line Code
Sets the DTE side line coding. The choices are AMI and B8ZS.
T1-DTE DSX Level
This field specifies the DTE DSX1 interface output level. The choices are
0-110 ft, 111-220 ft, 221-330 ft, 331-440 ft, 441-550 ft, 551-660 ft, and LONG.
D/I Start Channel
Selects the first channel in the block of channels assigned to the T1 DTE, from 1
through 24.
